BACKGROUND

Developing intelligent systems which take into consideration theeconomical, environmental, and safety factors of the modern society, isone of the main challenges of this century. Progress in the fields ofmobile robots, control architectures, artificial intelligence, advancedtechnologies, and computer vision allows us to now envisage a smartenvironment future.

It is safe to say that we are at the start of another industrialrevolution. The rise of the connected objects known as the “Internet ofThings” (IoT) will rival past technological marvels, such as theprinting press, the steam engine, and electricity. From the developedworld to developing world, every corner of the planet will experienceprofound economic resurgence. Even more remarkable is the speed withwhich this change will happen. A decade ago, there were about onebillion devices connected to internet. Today, there are close to 20billion. In five years, it could be close to 50 billion.

The rise of IoT also means we are at the start of a new age of data. Twochief components of an “IoT object” are its ability to capture data viasensors and transmit data via the Internet. The declining cost ofsensors since the start of the new millennium has been a main driver inthe rise of IoT. In short, sensors are dirt cheap today. This hasprofound implications on the ability to capture data.

The Internet of Things (IoT) describes a worldwide network ofintercommunicating devices. Internet of Things (IoT) has reached manydifferent players and gained further recognition. Out of the potentialInternet of Things application areas, Smart Cities (and regions), SmartCar and mobility, Smart Home and assisted living, Smart Industries,Public safety, Energy & environmental protection, Agriculture andTourism as part of a future IoT Ecosystem have acquired high attention.

The Internet of Everything (IoE) is a concept that aims to look at thebigger picture in which the Internet of Things fits. Yet, when you lookdeeper at IoE, you'll notice it really is also about the vision of adistributed network with a growing focus on the edge in times of ongoingdecentralization, some digital transformation enablers and a focus onIoT business outcomes.

While the Internet of Things today mainly is approached from theperspective of connected devices, their sensing capabilities,communication possibilities and, in the end, the device-generated datawhich are analyzed and leveraged to steer processes and power numerouspotential IoT use cases, the Internet of Everything concept wants tooffer a broader view.

The IoT based smart environments represent the next evolutionarydevelopment step in industries such as construction, manufacturing,transportation systems and even in sporting goods equipment. Like anyfunctioning organism, the smart environment relies first and foremost onIoT sensor data from the real world. Sensory data comes from multiplesensors of different modalities in distributed locations. The smartenvironment needs information about all its surroundings as well asabout its internal workings.

The challenge is determining the prioritized hierarchy of: (1) detectingthe relevant quantities, (2) monitoring and collecting the data, (3)assessing and evaluating the information, and (4) performingdecision-making actions. The information needed by smart environments isprovided by Distributed Sensor Systems, which are responsible forsensing as well as for the first stages of the processing hierarchy.

New types of applications can involve the electric vehicle and the smarthouse, in which appliances and services that provide notifications,security, energy-saving, automation, telecommunication, computers andentertainment are integrated into a single ecosystem with a shared userinterface. Obviously, not everything will be in place straight away.Developing the technology, demonstrating, testing, and deployingproducts, it will be much nearer to implementing smart environments by2020. In the future computation, storage and communication services willbe highly pervasive and distributed: people, smart objects, machines,platforms, and the surrounding space (e.g., with wireless/wired sensors,M2M devices, etc.). The “communication language” will be based oninteroperable protocols, operating in heterogeneous environments andplatforms. IoT in this context is a generic term and all objects canplay an active role thanks to their connection to the Internet bycreating smart environments, where the role of the Internet has changed.

5th generation low earth satellite wireless systems are on the horizonand IoT is taking the center stage as devices are expected to form amajor portion of this 5G network paradigm. IoT technologies such asmachine to machine communication complemented with intelligent dataanalytics are expected to drastically change landscape of variousindustries. The emergence of cloud computing and its extension to fogparadigm with proliferation of intelligent ‘smart’ devices is expectedto lead further innovation in IoT.

The existing 5G (fifth generation wireless) networks have been widelyused in the Internet of Things (IoT) and are continuously evolving tomatch the needs of the future Internet of Things (IoT) applications. The5G (fifth generation) networks are expected to massive expand today'sIoT that can boost cellular operations, IoT security, and networkchallenges and driving the Internet future to the edge. The existing IoTsolutions are facing a number of challenges such as large number ofconnection of nodes, security, and new standards.

The drive to minimize human interaction in transportation vehicles isstronger than ever, especially in public transportation, automobiles,etc. For instant, just a few years ago, automobiles seldom had verysophisticated safety systems. Now, it is rare to find an automobilewithout various safety and protection systems. And now new technology isevolving to the point of being able to offer preventive methods tobetter manage and dissipate sudden impact energy to the vehicle.

Today internet of things is a new revolution of the internet. A worldwhere the real, digital and the virtual are converging to create smartenvironments that make energy, transport, cities, and many other areasmore intelligent. Different types of application like water monitoring,water pollution, air pollution, forest fire detection, smart homes,smart cities where each thing can connect from anywhere to anyplace tomake our life easier.

To understand what the constituents of IoE are we will need to dive intothe core parts of IoE. IoE is an umbrella term combining the following 4properties in one place:

1. People:

People are the humans using connected devices to deliver insights abouttheir personal and professional self. This data can include interests,preferences, work, personal health, etc. Connecting this data toenterprise needs can provide insights relating the needs and desires ofprospects for businesses. Additionally, this can be used to trackperformance and pain points of human resources.2. Process:The process is the way to ensure deliverability of right data at theright time to the right person or machine. Here data is more aboutinsightful information or an action than just random chunk. Figuring outa way to decipher the right flow of information is a key to making thebest use of big data.3. Data:With the increase in sources and types of data, we will also need toclassify the information and analyze it to bring useful insights. Dataalone is nothing but once combined with analytics and analysis this newdata can help businesses in decision making and managing theorganization.4. Things:This is where we come across the term Internet of Things (IoT). Internetof things is the interconnectivity of devices that send and receiveinformation across networks like the internet. With every signalinjected into the network, data is generated which needs to becollected, summarized, and analyzed efficiently.This application discloses an object control system (OCS) to controlnavigation of a moving vehicle when exiting from its own road or freewayto a new road or freeway. The new road or freeway is an underpass oroverpass and have no physical junction with the moving vehicle's ownroad or freeway. The moving vehicles obtains its navigation informationdata from the IoT network it is registered with and a plurality ofstationary objects near and in vicinity of an exit. The stationaryobjects during the time slots assigned to them by OCS transmitinformation data that assist moving vehicle navigating to the right laneand exit with the right speed. These stationary objects also provide anoperation information data that is used in the new road or freeway incase the vehicle exits to a road or freeway that belongs to a new cellwith different operation information data. All cells have an operationframe with the same duration, a time of day (TOD) for the start of thefirst frame, time slots with identical duration, number of total timeslots in the operation frame, and an absolute time that is a TOD for thestart of the first time slot. All objects within a cell function as anIoT device and use a time slot within the operation frame to broadcast atime stamp, the operation frame structure and the object's locationcoordinates.

FIG. 2 depicts wireless 4G, 5G, 6G (beyond 5G and 6G) and WiFi (wirelessfidelity) end to end Internet of Thing (IoT) networks 100 used by anobject's navigation and protection system (NPS). 4G network facilitatescommunication between user equipment (UE) or IoT device 110 and evolvedpacket core (EPC) 104 through evolved node B (eNodeB) 109 and IP(Internet protocol) network 106. 5G and 6G networks facilitatecommunication between UE or IoT device 112 and core network (CN) 104 aswell as beyond 5G/6G higher layers 105 through next generation Node B(gNodeB) 111 (or new NodeB) and IP network 106. WiFi network facilitatescommunication between UE or IoT device 108 and the cloud 101 throughWiFi router 107, and IP network 106. Cloud 101 accommodates EPC/CN 104and higher layers of beyond 5G/6G 105 as well as shared database (SD)102 and shared operation management center (SOMC) 103 and allows UEs orIoT devices 108, 110 and 112 have access to SD 102 and SOMC 103. SD andSOMC are used by all 5G (beyond 5G), 6G (beyond 6G), 7G, and WiFinetworks that belong to various service providers. SD stores allinformation data related to IoT devices that directly communicate(master IoTs) with IoT network. SOMC controls and manages the objectsthat use an IoT device (master IoT device).

In wireless 4G, 5G, 6G, (beyond 5G/6G), 7G, and WiFi networks there is aneed for synchronization. There are several synchronization techniquesused in data communication networks and the most common one depending onrequirements of network components or ports are syncE, Institute ofElectrical and Electronic Engineering IEEE1588 Precision Time ProtocolPTP, NTP, and GPS. The Network Time Protocol (NTP) is a networkingprotocol for clock synchronization between computer systems overpacket-switched, variable-latency data networks. In operation sincebefore 1985, NTP is one of the oldest Internet protocols in current use.Synchronous Ethernet, also referred to as SyncE, is an ITU-T standardfor computer networking that facilitates the transference of clocksignals over the Ethernet physical layer. This signal can then be madetraceable to an external clock. IEEE 1588 Precision Time Protocol (PTP)is a packet-based two-way communications protocol specifically designedto precisely synchronize distributed clocks to sub-microsecondresolution, typically on an Ethernet or IP-based network. GlobalSatellite Positioning System (GPS) signal is received, processed by alocal master clock, time server, or primary reference, and passed on to“slaves” and other devices, systems, or networks so their “local clocks”are likewise synchronized to coordinated universal time (UTC).

In wireless 4G, 5G, 6G, (beyond 5G/6G), 7G, and WiFi network 100 whenthe link between two network component ports is Ethernet then there is aneed to synchronize the two network components using SyncE, IEEE1588(PTP) or NTP depending on requirements and specification of two networkcomponents.

Mobile UE or IoT devices 108, 110, and 112 may use GPS to obtain time ofday (TOD), location coordinate and over the air protocol to achievefrequency and phase synchronization. However, for UEs or IoT devicesthat either cannot see the GPS satellites, GPS signal is very weak, orGPS receiver increases cost, size, and power consumption anothertechnique to acquire time of day is required. UEs and IoT devices canuse their received wireless 4G, 5G, 6G, (beyond 5G/6G), 7G, and WiFisignal to achieve frequency and phase synchronization. UEs and IoTdevices that do not have access to GPS signal can either obtain time ofday from UEs and IoT devices in surrounding environment that have accessto GPS signal and are accessible or obtain it from eNodeB, gNodeB andWiFi router that they communicate with.

There are three techniques that UEs and IoT devices can use to obtaintime of day from eNodeB, gNodeB and WiFi router. The precision of timeof day will be different using these three techniques. Time of day withdifferent accuracies is used for different applications. The lessaccurate (within fraction of microsecond, approximately 200 nanosecondor less) TOD uses one way communication between eNodeB, gNodeB and WiFirouter and UEs or IoT devices 108, 110, and 112. The more accurate(within 100 nanosecond) TOD uses two-way communications between eNodeB,gNodeB and WiFi router and UEs or IoT devices 108, 110, and 112. In allmethods eNodeB, gNodeB and WiFi router should have TOD. When eNodeB,gNodeB and WiFi router do not have TOD or cannot support exchange of TODwith UEs and IoT devices then the network component prior to eNodeB,gNodeB and WiFi router can be used to propagate TOD to UEs and IoTdevices 108, 110, and 112 with less accuracy. Both eNodeB, and gNodeBfrom 4G, 5G, 6G, and 7G network that support Remote Radio Unit (RRU),and Radio Unit (RU) can be terrestrial RRU/RU or low earth orbitsatellite RRU/RU.

In one embodiment, 4G, 5G, 6G, (beyond 5G/6G), 7G, and WiFi network 100provide TOD to UEs and IoT devices, using institute of electrical andelectronic engineering (IEEE1588) precision time protocol (PTP).IEEE1588 PTP exchanges the timing messages to and from UEs or IoTdevices 108, 110, and 112 and one component of 4G, 5G, 6G, (beyond5G/6G), 7G, and WiFi wireless networks 100.

The 4G, 5G, 6G, (beyond 5G/6G), 7G, and WiFi wireless networks 100 sendstime of day to UEs and IoT devices 108, 110, and 112 by cyclic prefix ofOFDM (orthogonal frequency division multiplexing) symbols from eNodeB,gNodeB and WiFi router where IFFT (inverse fast Fourier Transform) isperformed. In another technique the 4G, 5G, 6G, (beyond 5G/6G), 7G, andWiFi network 100 utilizes unused downlink sub-carriers or unused bits ormessages in various downlink channels to send time of day to UEs or IoTdevices 108, 110, and 112. All components of 4G, 5G, 6G, (beyond 5G/6G),7G, and WiFi network 100 are time synchronized and have the same time ofday. The 4G, 5G, 6G, (beyond 5G/6G), and 7G networks may transmitEthernet packets over the air to UEs or IoT devices 108, 110, and 112 tohave an end-to-end network using a single packet protocol. By doing thisboth hardware and software is significantly simplified.

Some UEs and IoT devices 108, 110, and 112 obtain time of day from otherUEs or IoT devices in surrounding environment that are in theircommunication range and have time of day. They use another frequency tocommunicate with other UEs and IoT devices in surrounding environmentand exchange broadcast and Ethernet packets. The UEs and IoT devices108, 110, and 112 may communicate with other UEs and IoT devices byexchanging Ethernet packets or any other proprietary packets.

The UEs and IoT devices may use similar physical layer as 4G, 5G, 6G,(beyond 5G/6G), 7G, or WiFi to communicate with or broadcast theirinformation data to other UEs and IoT devices in their surroundingenvironment without introducing any unwanted interference. They also mayuse a proprietary physical layer to communicate with or broadcast theirinformation data to other UEs and IoT devices in their surroundingenvironment without introducing any unwanted interference. The UEs andIoT devices may support Bluetooth, Zigbee, infrared, WiFi, and any otherwireless communication systems to communicate with other UEs and IoTdevices in their surrounding environment and exchange information dataand transmit and receive broadcast data. The communication between UEsand IoTs devices is encrypted and highly secured.

The UEs and IoT devices transmit and receive broadcast data thatincludes the type of UE and IoT device, their IP address, their locationcoordinate, their mass, time of day, method of obtaining time of day.

FIG. 3A depicts 5G/6G end to end IoT network 200 and FIG. 3B illustratesbeyond 5G/6G end to end IoT network 250 supporting cloud radio accessnetwork C-RAN, virtual radio access network vRAN, and open radio accessnetwork (O-RAN). The 5G/6G network 200 facilitate communication betweenUE or IoT device 209 and core network (CN) 201 through RU 207,distributed unit (DU) 205, and central unit (CU) 203 using over the airprotocol interface 208, evolved common public radio interface (eCPRI) ornext generation fronthaul interface (NGFI) 206, F1 interface 204 and“NG” interface 202. The RU 207, DU 205, and CU 203 are components of5G/6G new radio (NR) which is also called gNodeB. UEs 209 also act as anIoT (IoE) device.

The 5G/6G network 200 uses different architectures depending onapplications that the network is used for. In certain architectures oneor more network components are collocated. When one or more networkcomponents are collocated the components use the interfaces defined inthe standard. However, there are cases such as a small cell when two ormore components of network are collocated, and the interfaces may beeliminated.

Cloud radio access network or C-RAN architectures shown in FIG. 2enables cost saving on expensive baseband resources, in which thebaseband units are shared in a centralized baseband pool. Therefore, thecomputing resources can be utilized optimally based on the demand. C-RANarchitecture has also opened an opportunity for RAN virtualization(vRAN) to further reduce cost. Therefore, virtual RAN or vRAN has beendeveloped to simplify the deployment and management of the RAN nodes andmake the platform readily available for multitude of dynamicallychanging service requirements. The main issue with C-RAN and vRAN isthat these architectures still utilize propriety software, hardware andinterfaces which lack openness as a major bottleneck in efficientlyutilizing virtualization. To overcome the limitations of C-RAN and vRAN,O-RAN is emerging as a new RAN architecture that uses open interfacesbetween the elements implemented on general-purpose hardware. Thisallows operators select RU and DU hardware and software from differentvendors. In addition, open interfaces between decoupled RAN componentsprovide efficient multi-vendor interoperability. O-RAN architecture alsoallows enhanced RAN virtualization that supports more efficient splitsover the protocol stack for network slicing purpose. O-RAN furtherreduces RAN expenditure by utilizing self-organizing networks thatreduce conventional labor-intensive means of network deployment,operation, and optimization. In addition to cost reduction, intelligentRAN can handle the growing network complexity and improve the efficiencyand accuracy by reducing the human-machine interaction.

FIG. 3B shows the O-RAN end to end architecture (UE, gNodeB) 250 forbeyond 5G and 6G. Higher layers 251 communicate with open interface 252to central unit 253. The interface between central unit (CU) 253 anddistributed unit (DU) 255 is open interface 254 “F1” and the interfacebetween distributed unit 255 and radio unit (RU) 257 is open fronthaul256. UE or IoT device 259 use over the air interface 258 to communicatewith RU 257. Therefore, the only difference between 5G/6G, beyond 5G and6G ORAN architecture is open interface 252, open “F1” interface 254 andopen fronthaul 256. All embodiments related to 5G/6G explain above applyto beyond 5G and 6G (7G) ORAN.

FIG. 4 shows the architecture of an IoT sensor network 400. In general,IoT sensor network 400 communicates with 5G, 6G, beyond 5G/6G (or 7G)and WiFi networks to exchange information data. IoT sensor network 400through radio 403 attaches itself to a 5G, 6G, beyond 5G/6G (or 7G) orWiFi network in its surrounding environment that supports Internet ofThings (IoT) and listens to commands to activate sensor network 410 ₁ to410 _(n). Radio 403 when receives a command, sends it to CPU 405 to beevaluated and executed by CPU 405 or sensor network 410 ₁ to 410 _(n)that is connected to CPU 405.

FIGS. 5 and 6 depict hexagon geometry 600 for terrestrial and satelliteapplication. The design objective of early mobile radio systems was toachieve a large coverage area using a single high-power transmitter withan antenna mounted on a tall tower. A cellular concept is a system-levelidea which calls for replacing a single high-power transmitter (largecell) with many low power transmitters (small cell) each providing acoverage to only a small portion of the service area.

When considering geometric shapes which cover an entire region withoutoverlap and with equal area, there are three sensible choices—a square,an equilateral triangle, and a hexagon. For a given distance between thecenter of a polygon and its farthest perimeter points, the hexagon hasthe largest area of the three. Thus, by using hexagon geometry, thefewest number of cells can cover a geographic region, and hexagonclosely approximates a circular radiation pattern which would occur foran Omni-directional base station antenna and free space. When usinghexagon, base station transmitter (RU, or RRU) is in the center of thecell (Omni-directional antenna) or on the three of the six cell vertices(directional antenna).

Each cellular base station (RU, RRU, gNodeB, eNodeB), or proprietarybase station is allocated a group of radio channels to be used within asmall geographic area called cell. Base stations (RU, RRU, eNodeB,gNodeB, or proprietary) in adjacent cells are assigned channel groupswhich contain completely different channels than neighboring cells. Bylimiting the coverage area to within the boundaries of a cell, the samegroups of channels may be used to cover different cells that areseparated from one another by distances large enough to keep theinterference levels within tolerable limits. The design process ofselecting and allocating channel groups for all the cellular basestations (RU, RRU, eNodeB, gNodeB, or proprietary) is called frequencyreuse or frequency planning.

Advances in interference cancellation techniques today allow a receiverto operate with higher levels of co-channel interference. The motivationof improving a receiver's performance in co-channel interference is toincrease the spectrum efficiency of a system usually by allowing agreater geographical re-use of frequencies. It is a general principlethat a communication system should be designed to avoid interference inthe first place, either through network planning or with effective radioresource management and medium access control.

Terrestrial base stations (RU, RRU, eNodeB, gNodeB, or proprietary) arestationary and located in the center (or vertices) of a hexagon cell asshown in FIG. 5 . The terrestrial cluster 601 has a center cell 602 and6 cells attached to its peripheral. This cluster grows by adding newcells to expand the coverage area. Cells in the architecture of FIG. 5and the moving objects within the cells are all controlled by SOMC. Theshared database SD stores location coordinate of the base stations (RU,RRU, eNodeB, gNodeB, or proprietary), type of base stations (sectors,transmit power, height of antenna, type of tower, service providersusing the tower, type of power supply), the terrain map of the cells,street and road map of the cells, one way or two way roads, allowed ornot allowed right turn at red light, location coordinates of junctionsand traffic lights, type of junctions, type of street and road (onelane, two lanes, multiple lanes, road and street curbs and centerbarriers), type of stationary objects in the cells, type of buildings(height, type of body structure), specific information for movingobject's navigation and protection system (NPS), and service providersusing the cells. Some of the data in SD are fixed and some dynamicallychange.

For flying objects, it is also possible to use hexagon cell architectureas shown in FIG. 6 . They can be called satellite clusters 603 becauseeach cell 604 needs to cover a much wider area compared with terrestrialcells. In other words, a satellite cell can cover an area that multipleof terrestrial cells cover. The base stations (RU, RRU, eNodeB, gNodeB,or proprietary) serving satellite cells are either fix or mobile.

Fix base stations are the same as base stations for terrestrial cells.The only difference is elevation of the antenna and antenna radiationpattern. For satellite base station a very tall tower or a very tallbuilding can be used to provide coverage for a wide area. The radiationpattern of the antenna is also important. The pattern needs to minimizeany radiation towards the ground. Due to high elevation of antenna andthe specific radiation pattern the waves travel in free space withminimum multipath fading.

Moving base stations 606 are either flying balloons or low orbitsatellite. These base stations provide RU and RRU and possibly morefunctions of eNodeB, gNodeB, and proprietary base station. Satellite andballoon base station (RU, RRU, eNodeB, gNodeB, or proprietary) can alsoserve the moving objects on the ground due to less multipath fading. Themain issue with moving satellite base stations is their latency.However, if low orbit satellite is used the latency can be reduced toaround 20 milliseconds. Like terrestrial cells, satellite cells also useSD and SOMC and store all their information, specification, andcapabilities in the SD to be used by SOMC to control navigation andprotection system (NPS) of both moving objects and flying objects.

FIG. 7 shows moving and flying objects control system (OCS) 700. Theobject control system 700 uses SOMC (702) and SD (701) to control thenavigation and protection of moving and flying objects that support IoTnetwork and IoT devices in a smart environment. Object control system700 uses time of day (TOD) to schedule activities of the moving (703),flying (704), and stationary (705) in the smart environment to allow allobjects within object control system 700 operate freely with nointerference and collision.

Each object (703, 704, and 705) has a plurality of IoT devices. One IoTdevice is a master IoT device, and the rest are slave IoT devices thatuse IEEE1588 protocol to achieve clock synchronization and obtain timeof day from the master IoT device. The master IoT device through IoTnetwork exchange necessary information data with SOMC 702 and SD 701 andcommunicates with slave IoT devices to share operation information data(OID). A slave IoT device can also obtain TOD from another IoT device.

In general, the smartenvironment 800 in addition to open space consists of variousstationary, moving, and flying objects (IoT devices) that are capable ofwirelessly communicate with other objects (IoT devices) as well as apublic or private communication network.

FIG. 9A depicts OFDM transmit symbol signal 810 before adding cyclicprefix. 5G, 6G (7G), beyond 5G and 6G use OFDM (orthogonal frequencydivision multiplexing) in their transmit path. The duration of transmitsignal is one OFDM symbol 811 for 4G eNodeB and 5G (6G) gNodeB. Thetransmit signal 850 consists of “n” samples x₁ to x_(n) 812. Toeliminate inter-symbol interference “n−m” samples 813 from end of OFDMsymbol are copied at the beginning of symbol or some samples from thebeginning of OFDM symbol are copied at the end of symbol. The “m to n”samples are called cyclic prefix and the duration of it depends onradius of coverage of RRU and RU transmitters. These “m to n” samples atthe receiver of user equipment UE (IoT device) are removed by usingcorrelation before performing the receiver functions.

FIG. 9B shows transmit signal with cyclic prefix 814 that is added atthe beginning of transmit symbol which consists of “n” samples x₁ tox_(n) 812. Samples x_(m) to x_(n) from end of transmit symbol are copiedat the beginning of “n” samples x₁ to x_(n) as cyclic prefix 814. In theUE (IoT device) receiver cyclic prefix 814 is removed from receivedsignal before the receive process starts. The process of removal ofcyclic prefix is a circular correlation. The highest correlation isachieved when all samples in cyclic prefix are matched. There is alwayspossible one or more samples in cyclic prefix are not matched due tovarious impairment and results in lower amount of correlation but stillremoval of cyclic prefix is possible. Therefore, it is possible to useone or more samples in cyclic prefix to transmit time of day to userequipment UE (IoT device).

In one embodiment of transmit signal 810 one or more samples of cyclicprefix 814 samples x_(m) to x_(n) is used to send the time of day touser equipment UEs or IoT devices.

In another embodiment the number of samples in cyclic prefix are morethan needed for operation and the extra samples (one or more) are usedto send time of day and date.

In another embodiment the samples used from cyclic prefix 814 fortransmitting time of day are at the start, middle, or end of cyclicprefix 814.

In another embodiment the samples used from cyclic prefix 814 fortransmitting time of day are at any location in cyclic prefix 814 andthe location do not change until TOD data is transmitted.

In one embodiment the time of day is sent to user equipment UEs, or IoTdevices over several transmit OFDM symbols.

In one embodiment the time of day includes date and time of day and dateinclude year, month, and day.

In one embodiment the bits in samples from cyclic prefix 814 are usedfor transmission of time of day to UEs or IoT devices.

In another embodiment the top bits in sample (x_(m)) 815 of cyclicprefix are used to send time of day to mitigate effect of any noise,interference or fading.

In one embodiment only one sample of cyclic prefix 854 is used fortransmitting the time of day and the first sample that is used for timeof day has a detectable bit pattern to indicate that next samples at thesame location in next cyclic prefixes contain the time of day.

In one embodiment, more than one sample of cyclic prefix 814 is used fortransmitting the time of day and the first samples that are used fortime of day have a detectable bit pattern to indicate that next sampleswhether in present cyclic prefix or next cyclic prefixes contain thetime of day.

In another embodiment the first sample of first cyclic prefix carriesthe hour, the first sample of second cyclic prefix carries the seconds,the first sample of third cyclic prefix carries the milliseconds, thefirst sample of forth cyclic prefix caries the microseconds, the firstsample of fifth cyclic prefix caries nanoseconds, and if more accuraciesare available the first sample of sixth cyclic prefix carries thepicoseconds.

In one embodiment the bits used to represent the time of day arecompressed (using one of compression algorithms) to use less cyclicprefix samples for transmission of time of day.

There is a time difference between transmissions of two cyclic prefixes.During this time difference the date, hour (T_(h)), second (T_(s)),millisecond (T_(m)), microsecond (T_(μ)), or nanosecond (T_(n)) of timeof day can be incremented and this creates a significant time errorbetween RU/RRU and UEs or IoT devices. Therefore, before sending time ofday there is a need to find out if one of (T_(h)), (T_(s)), (T_(m)),(T_(μ)), or nanosecond (T_(n)) will be incremented during thetransmission of complete time of day.

In one embodiment the date, hour (T_(h)), second (T_(s)), millisecond(T_(m)), microsecond (T_(μ)), or nanosecond (T_(n)) of time of day ifneeded is incremented before being sent to UE or IoT device.

In another embodiment, the time of day before being sent to UE or IoTdevice is adjusted for propagation time of IFFT through transmitter pathof RU/RRU or BBU/DU up to antenna to reduce the time error between timeof day at RU/RRU (or BBU/DU) and UEs or IoT devices.

In one embodiment the date and time of day that is sent to UE or IoTdevice is repeated or updated with a configurable time interval.

FIG. 9C depicts a typical coverage of RRU/RU in a 4G, 5G, 6G, or (7G)wireless network. UEs or IoT devices A, B, and C are at differentdistance from RU/RRU. Therefore, UEs or IoT devices A, B, and C receivetime of day at different time which results in time error between UEs orIoT devices. These UEs or IoT devices when transmit to RU/RRU need toadjust their transmission time based on their time alignment or timeadvance which compensate for their difference in distance from RRU/RU.The time alignment or time advance is used to eliminate the error intime of day at UEs or IoT devices A, B, and C and make all UEs or IoTdevices have the same time of day.

In one embodiment UEs or IoT devices that are at different distance fromtheir common RRU/RU use their time alignment or time advance to adjustthe time of day received from RRU/RU to have the same time of day.

In 4G, 5G, and 6G (or 7G) it is possible to use downlink methods likecyclic prefix to transmit time of day to UEs or IoT devices. Thesemethods can utilize unused subcarriers or unused bits or messages invarious downlink channels. For instance, in 4G (as well as 5G and 6G)LTE there are two cell search procedures: one for initialsynchronization and another for detecting neighbor cells in preparationfor handover. In both cases the UE or IoT device uses two specialsignals broadcast on each RRU: Primary Synchronization Sequence (PSS)and Secondary Synchronization Sequence (SSS). The detection of thesesignals allows the UE or IoT device to complete time and frequencysynchronization and to acquire useful system parameters such as cellidentity, cyclic prefix length, and access mode (FDD/TDD).

In the frequency domain, the PSS and SSS occupy the central six resourceblocks (RBs, 72 subcarriers), irrespective of the system channelbandwidth, which allows the UE or IoT device to synchronize to thenetwork without a priori knowledge of the allocated bandwidth. Thesynchronization sequences use 62 sub-carriers in total, with 31sub-carriers mapped on each side of the DC sub-carrier which is notused. This leaves 5 sub-carriers at each extremity of the 6 central RBsunused. These 10 unused sub-carriers can be used to transmit time of dayto UEs or IoT devices. Like cyclic prefix the time of day should beadjusted for propagation time through transmitter path up to transmitantenna port in order to minimize time difference between gNodeB/eNodeB(RU/RRU) and UEs or IoT devices. During transmission of the time of dayit is possible one of (T_(h)), (T_(s)), (T_(m)), (T_(μ)), and (T_(n))has to be incremented before being sent to UEs or IoT devices due to thetime it takes to transmit the time of day.

In one embodiment unused downlink sub-carriers is used to transmit timeof day to UEs or IoT devices.

It is also possible to utilize unused bits or messages in variousdownlink channels of 4G, 5G, or 6G (7G) to transmit the time of day likeunused sub-carriers.

In another embodiment unused bits or messages of various downlinkchannels is used to transmit time of day to UEs or IoT devices.

In one embodiment when unused downlink sub-carriers, bits, or messagesare used, due to the time takes to send all the data, the day, hour(T_(h)), second (T_(s)), millisecond (T_(m)), microsecond (T_(μ)), ornanoseconds (T_(n)), of time of day if needed is incremented beforebeing sent to UE or IoT device.

Using time advance or time alignment allows all IoT devices have thesame TOD. However, this IoT-device-TOD is not the same as TOD thateNodeB, gNodeB, WiFi wireless router, or proprietary base station(terrestrial, low earth orbit satellite, or balloon) holds. Thedifference between IoT-device-TOD and the IoT network TOD (eNodeB,gNodeB, WiFi wireless router, or proprietary base station) is thedistance between closest IoT device to IoT network antenna (eNodeB,gNodeB, WiFi wireless router, or proprietary base station). One way toeliminate or remove this difference is to have a local IoT devicelocated at the Radio Unit (RU, RRU) of the eNodeB, gNodeB, WiFi wirelessrouter, or proprietary base station. This local IoT device reduces thedifference between IoT-device-TOD and network TOD to a negligible amountas well as provide monitoring of the eNodeB, gNodeB, WiFi wirelessrouter, or proprietary base station for functionality, control,management, configuration, and maintenance. It is assumed TOD thateNodeB, gNodeB, WiFi wireless router, or proprietary base station sendsto IoT device is the TOD at the transmit antenna port of RU, RRU,wireless router or proprietary base station.

All Low earth orbit satellite RU, flying balloon RU, microcell RU, andmacro-cell RU base stations need to have a local IoT device next to theantenna of RU (base station) to minimize the difference betweenIoT-device-TOD and IoT network TOD. In case of small cell RU (or basestation) a local IoT device or UE close to the antenna of small cell RUis needed if the operating coverage radius of small cell RU or basestation is less than 100 (330 feet) meters.

In cases that two independent IoT devices obtain TOD from twoindependent base station (eNodeB, gNodeB, WiFi wireless router, orproprietary) their obtained TOD will be different with an unspecifiedand random error. However, if all Base stations (eNodeB, gNodeB, WiFiwireless router, or proprietary) use a local IoT device which is closeto the transmitter and receiver antenna, then all IoT devicesirrespective of their base station will have the same TOD with verynegligible error. Using a local IoT device near base station antennaalso allows to use time alignment or time advance to estimate thedistance of an IoT device from the base station it is communicatingwith.

There is another issue when IoT device uses IEEE1588 PTP to obtain TODfrom base station (eNodeB, gNodeB, WiFi wireless router, orproprietary). Both IoT device and base station use different time fortransmit and receive processing. This processing time may dynamicallychange due to load. Therefore, to use PTP the processing delay andpropagation (up to transmit antenna port and from receiver antenna port)delay in transmit and receive paths for both IoT device and base stationare required to be known and considered in PTP messages. It is easy forIoT device to consider the delay in transmit and receive path in its PTPmessages. Base station uses components from various suppliers and caneither use a local IoT device to estimate the processing and propagation(within transmitter and receiver) delay or use SON (self-organizingnetwork) to estimate the processing and propagation delay. However, itmay not be possible to estimate the delay with acceptable accuracy andthe error depends on the point or port in base station link that PTPmessages are generated and terminated.

The advantage of unidirectional transmission of TOD from base station(eNodeB, gNodeB, WiFi wireless router, or proprietary) to IoT device isthat it is simple, more accurate, only IoT device receiver is involvedfor stationary IoT devices, and all stationary IoT devices (master orslave) can independently obtain TOD by only having a receiver thatreceives the base station downlink signal. Stationary IoT devices timealignment or time advance is constant because base station uses a localIoT device which set the reference and is stationary. Therefore, allstationary IoT devices use their time alignment or time advance (whichindicates the distance between IoT device and base station) that doesnot change and is constant to adjust the TOD they receive from basestation to the current TOD base stations (eNodeB, gNodeB, WiFi wirelessrouter, or proprietary) has at the time IoT device receives the old TOD.

In cases that a base station (eNodeB, gNodeB, WiFi wireless router, orproprietary) in its system information sends its location coordinates(FIG. 9D), IoT devices do not need to use time alignment to adjust theirtime of day to base station current TOD. In this scenario, IoT deviceonly uses its receiver to obtain the TOD. The TOD is transmitted to IoTdevice using base station's (RU, RRU) system information, cyclic prefix,downlink unused subcarriers, and downlink unused messages. The TOD is atthe antenna port of base station (RU, RRU). IoT device uses its ownlocation coordinates obtained from a GPS receiver and base station'slocation coordinates received through system information to estimate itsdistance from base station (eNodeB, gNodeB, WiFi wireless router, orproprietary). Then IoT device uses its distance from base station(converted to nanosecond) to adjust and synchronize the received TODfrom base station (RU, RRU) to the time of day at the base station. Byusing this technique with a simple receiver an IoT device can obtain acurrent TOD from a base station (eNodeB, gNodeB, WiFi wireless router,or proprietary). Using location coordinates in estimating TOD by an IoTdevice is not without any error. Simple GPS receivers estimate thelocation coordinates within 5 meters (or 15 nanosecond). Therefore, ifwe assume maximum location coordinate error at IoT device and the basestation then the adjusted TOD at IoT device could have a maximum errorof 30 nanosecond. This is an acceptable error because TOD obtained froma GPS receiver is within 100 nanosecond error from UTC time of day. Incase of mobile base station (low earth orbit satellite RU) the vehicleappears stationary to the mobile base station due to small propagationdelay (around 20 milliseconds) from mobile base station (low earth orbitRU) to moving vehicle. In 20 millisecond a vehicle with 70 miles an hourspeed moves around 2 feet. Therefore, if mobile base station (low earthorbit RU) in its system information sends its location coordinates and atime stamp indicating the TOD at the antenna of the RU then movingvehicle can calculates its distance from the base station (low earthorbit RU) and update its TOD. To do this the mobile base stationrequires to update its location coordinate with high frequency(proportional to its speed) to minimize the error in calculating thedistance between moving vehicle and the mobile base station (low earthorbit RU) and updated TOD at moving vehicle. In case the mobile basestation is a balloon the propagation delay between IoT device (themoving vehicle) and the balloon is low and may be comparable withterrestrial base station. Both moving vehicle and the balloon have lowspeed. Therefore, a moving balloon base station looks like terrestrialbase station for moving vehicle.

An IoT device can also obtain or update its TOD using another IoT device(FIG. 9D) in its surrounding environment. All IoT devices obtain theirlocation coordinates from GPS or other means. IoT devices also includetheir location coordinates in their broadcast and Ethernet packets whenone is transmitted. An IoT device can use its own location coordinatesand the location coordinate of another IoT device to estimate thedistance between them. Then an IoT device uses its distance from anotherIoT device, and the time stamp it receives from another IoT device toupdate its own TOD.

FIG. 9D illustrates method 840 where IoT device uses cyclic prefix,unused subcarriers, or downlink system information to obtain TOD. TheeNodeB or gNodeB 842 uses either GPS receiver 841 or IEEE1588 PTP frommaster network unit 843 to achieve clock synchronization and obtain TOD.IoT1 device 844 and IoT2 device 845 with distance D1 and D2 from eNodeBor gNodeB 842 both frequency and phase synchronize with the eNodeB orgNodeB 842 using over the air protocol. IoT1 device 844 and IoT2 device845 receive TOD through cyclic prefix, unused sub-carriers, systeminformation, or unused bits and messages from eNodeB or gNodeB 842.Since IoT1 device and IoT2 device are at difference distances D1 and D2from eNodeB or gNodeB 842 then time alignment or time advance is used toadjust time of day that IoT1 device and IoT2 device received from eNodeBor gNodeB 842. Time alignment or time advance for adjusting TOD may alsoconsider the received signal propagation time between antenna port anddecoder of IoT1 device or/and IoT2 device. For higher accuracy, IoT1 andIoT2 devices in addition to time advance or time alignment could adjustTOD by considering the transmit signal propagation time betweenmodulator and antenna port and the propagation time from their antennaport to their detector.

FIG. 10A depicts Ethernet frame 870 and broadcast frame 880.

In one embodiment the broadcast frame 880 uses similar structure asEthernet frame 870.

In one embodiment the broadcast frame 880 sends the time of day in thepayload.

In one embodiment the broadcast frame 880 instead of sending destinationaddress sends the time of day.

In another embodiment the source address (which is a media accesscontrol MAC address) of the broadcast frame 880 or an IP address is theidentity code of a transceiver (IoT device, sensor, WiFi router, RRU,RU, private base station, or any other wireless device).

In one embodiment, two wireless devices (IoT devices, sensors, andothers) use Ethernet packets or frame to exchange information betweenthem when both source and destination addresses are used to identify thetwo wireless devices. One wireless device retrieves the address ofanother wireless device from its broadcast packet and then usingEthernet packets establishes direct communication between them toexchange information data.

FIG. 10B shows two IoT devices 860. Both IoT1 device and IoT2 devicehave their clocks 863 and 865 frequency and phase synchronized witheNodeB, gNodeB or WiFi clock 864. IoT1 and IoT2 devices 866 and 867 cansupport a wireless sensor transceiver, a Bluetooth transceiver, a Zigbeetransceiver, an Infrared transceiver, a Radar transceiver, a Lidartransceiver, an ultrasonic transceiver, a WiFi transceiver, aproprietary transceiver, and a 4G, 5G, 6G, or 7G transceiver. IoT1 andIoT2 devices 866 and 867 use 4G, 5G, 6G, or 7G transceiver to obtainclock frequency and phase synchronization from 4G, 5G, 6G, or 7G eNodeB,gNodeB or WiFi 864. Both IoT devices support Radar, Lidar, ultrasonic,and Camera.

IoT1 clock 863 increments time of day 861 for IoT1 device 866 and IoT2clock 865 increments time of day 862 for IoT2 device 867. Both IoTdevices 866 and 867 use eNodeB, gNodeB 864, or WiFi to achieve clockfrequency and phase synchronization as well as obtaining time of day 861and 862. IoT1 device 866 and IoT2 device 867 can also use GPS to obtaintime of day and the clock. IoT1 device 866 and IoT2 device 867 shouldhave their transmit frequency +/−0.1 part per million (PPM) accuratecompared with the frequency they receive from eNodeB or gNodeB 864.Worst case scenario is when IoT1 device 866 transmit frequency is +0.1PPM compared with received frequency and IoT2 device 867 transmitfrequency is −0.1 PPM compared with received frequency from eNodeB orgNodeB 864. A difference of 0.2 PPM between IoT1 clock 863 and IoT2clock 865 produce very negligible error when used for incrementing IoT1time of day 861 and IoT2 time of day 862. In addition, IoT1 clock 863and IoT2 clock 865 as well as IoT1 TOD 861 and IoT2 TOD 862 arecontinuously updated to prevent error accumulation and maintain anyerror negligible.

There are several ways for an IoT device to obtain time of day (TOD).The technique or method an IoT device may use depends on type of IoTdevice and its capabilities. The methods available to obtain TOD are.

1. GPS: Using GPS receiver the TOD is obtained directly. However, usingGPS requires an accurate oscillator or clock that provides sufficienthold over when GPS signal is not available for a long period of time dueto jamming, spoofing and other technical problems. A good clock oroscillator makes the solution expensive and bulky for a simple cheap IoTdevice.2. IEEE1588 PTP: If the IoT device can communicate with IoT network,then it can use PTP protocol to obtain TOD. PTP accuracy depends onaccuracy of the propagation delay through various components of IoTnetwork. If an IoT device uses PTP protocol, then it needs to update theTOD on regular time interval to eliminate any drift due to its clock. IfIoT device uses an exactly accurate clock (atomic clock, OCXO) with goodhold over then it can maintain the TOD when the IoT network is notavailable (due to jamming, spoofing and other technical problems) forupdating the TOD.3. Unidirectional messages: This is another technique an IoT device thatcommunicates with IoT network can use to obtain TOD. In this method IoTnetwork uses downlink unused subcarriers, cyclic prefix, systeminformation, or unused messages to send the TOD to the IoT devices. IoTdevices use the received TOD and adjust it with their time advanced ortime alignment received from IoT network to have the same TOD. If oneIoT device located at the transmitter (RU) of the IoT network, then IoTdevices TOD is the time of day at the transmitter of IoT network. If IoTnetwork in its system information that it sends to IoT device includesits location coordinates, then an IoT device only requires to receiveTOD and IoT network's location coordinates and then adjusts its TOD tothe TOD at the antenna of IoT network transmitter by using the distancebetween IoT device and IoT network (distance obtained from locationcoordinates of IoT device and IoT network).4. Master IoT device (NPS): in a plurality of IoT devices when one ofthe IoT devices is a master IoT device and remaining are slave IoTdevices, the master IoT device may have capability to obtain TOD fromIoT network, GPS and other IoT devices (master or slave) that are notattached to it. Therefore, slave IoT devices within the plurality of IoTdevices obtain the TOD from master IoT device they are attached to. Theexchange of TOD is done wired or wireless using PTP messages.5. Blind search: This is the case when an IoT device can not access IoTnetwork (IoT network is down, jammed, spoofed, out of reach, or do nothave hold over capability), and does not have access to GPS satellite(no GPS receiver, GPS jammed or spoofed). Therefore, the only way toobtain time of day is from another IoT device that possesses TOD(through GPS receiver, holdover capability, or IoT network). In thisscenario IoT device uses exchange of time stamps to obtain TOD fromanother IoT device that possesses accurate TOD through broadcast andEthernet packets.6. In cases that a base station (eNodeB, gNodeB, WiFi wireless router,or proprietary) in its system information sends its locationcoordinates, IoT devices do not need to use time alignment to adjusttheir time of day to base station current TOD. In this scenario, IoTdevice only uses its receiver to obtain the TOD. The TOD is transmittedto IoT device using base station's (RU, RRU) system information, cyclicprefix, downlink unused subcarriers, and downlink unused messages. TheTOD is at the antenna port of base station (RU, RRU). IoT device usesits own location coordinates obtained from a GPS receiver and basestation's location coordinates received through system information toestimate its distance from base station (eNodeB, gNodeB, WiFi wirelessrouter, or proprietary). Then as shown in FIG. 9D, IoT device uses itsdistance from base station (converted to nanosecond) to adjust andsynchronize the received TOD from base station (RU, RRU) to the time ofday at the base station. By using this technique with a simple receiveran IoT device can obtain a current TOD from a base station (eNodeB,gNodeB, WiFi wireless router, or proprietary). Using locationcoordinates in estimating TOD by an IoT device is not without any error.Simple GPS receivers estimate the location coordinates within 5 meters(or 15 nanosecond). Therefore, if we assume maximum location coordinateerror at IoT device and the base station then the adjusted TOD at IoTdevice could have a maximum error of 30 nanosecond. This is anacceptable error because TOD obtained from a GPS receiver is within 100nanosecond error from UTC time of day. In case of mobile base station(low earth orbit satellite RU) the vehicle appears stationary to themobile base station due to small propagation delay (around 20milliseconds) from mobile base station (low earth orbit RU) to movingvehicle. In 20 millisecond a vehicle with 70 miles an hour speed movesaround 2 feet. Therefore, if mobile base station (low earth orbit RU) inits system information sends its location coordinates and a time stampindicating the TOD at the antenna of the RU then moving vehicle cancalculates its distance from the base station (low earth orbit RU) andupdate its TOD. To do this the mobile base station requires to updateits location coordinate with high frequency (proportional to its speed)to minimize the error in calculating the distance between moving vehicleand the mobile base station (low earth orbit RU) and updated TOD atmoving vehicle. In case the mobile base station is a balloon thepropagation delay between IoT device (the moving vehicle) and theballoon is low and may be comparable with terrestrial base station. Bothmoving vehicle and the balloon have low speed. Therefore, a movingballoon base station looks similar to terrestrial base station formoving vehicle.7. An IoT device can also obtain or update its TOD using another IoTdevice in its surrounding environment as shown in FIG. 9D. All IoTdevices obtain their location coordinates from GPS or other means. IoTdevices also include their location coordinates in their broadcast andEthernet packets when one is transmitted. An IoT device can use its ownlocation coordinates and the location coordinate of another IoT deviceto estimate the distance between them. Then an IoT device uses itsdistance from another IoT device, and the time stamp it receives fromanother IoT device to update its own TOD.

FIGS. 12A and 12B illustrate two typical streets or roads 940. FIG. 12Ashows a road with center barrier 946 and curb 942 at both side of theroad. The road shows two lanes at each direction, but it can have onelane or more than two lanes at each direction. FIG. 12B shows a road orstreet that has no center barrier. In each direction it can have one ormore lanes. In both FIGS. 12A and 12B the lanes are separated with lines944 and 951. Lane lines in FIGS. 12A and 12B also can come with studreflectors 945 and 952. Both roads shown in FIGS. 12A and 12B may alsouse stud reflectors 943, 950, and 947 along the side curbs 943, 949 andmiddle barrier 946. The spacing between studs can be equal or differentand depends on terrain topography.

The above type of roads are also used outside the cities or used to linkstates, towns, cities, and villages. When they are used for linking, theroads may not have the side curbs. When the roads 940 do not have sidecurbs studs 943 and 950 may have some distance from the side lines.

The studs (side curb, center barrier, and lane lines) in addition tobeing used as reflectors they can also act as stationary object in theobject control system (OCS). In OCS, studs are IoT devices that assistmoving objects navigation and protection system. The stud IoT devicesneed to be exceptionally low in cost. Therefore, not all stud IoTdevices communicate with IoT network and only limited stud IoT devices(master) communicate with IoT network to obtain TOD and operationinformation data (OID). The stud IoT devices (masters) that communicatewith IoT network are at locations that receive strong signal from IoTnetwork (GPS) and need lower transmit power to communicate with IoTnetwork. Stud IoT devices that do not communicate with IoT network areslave to the master stud IoT devices. The slave stud IoT devices aredaisy chained to the master stud IoT devices and receive their OID frommaster stud IoT devices. The studs IoT devices are powered with solarenergy individually or from a larger solar panel that can power severalstuds IoT devices. They can also be powered by other means.

A master stud IoT device receives one or more time slot with theirassociated absolute times. The number of slave stud IoT devices that areattached to a master stud IoT device is much higher than the number oftime slots assigned in OID to the master stud IoT device. Master studIoT device uses the time slots and creates a specific OID with one ofthe time slots and its absolute time for each slave stud IoT device.This specific OID has a schedule that depending on the environment doesnot allow two or more adjacent slave stud IoT devices transmit at thesame time using the same time slot. Even if master stud IoT device isassigned only one time slot, by using the frame duration (use one ormore adjacent frame) it can create a specific OID for each slave studIoT device in a way that two or more adjacent slave stud IoT device donot transmit at the same time during the same frame duration. This waynone of slave stud IoT devices transmit at the same time. In thesespecific OIDs the effective radiation power (ERP) also could bedifferent but within acceptable and pre-defined threshold. Therefore,master stud IoT device uses operation frame, time slot, absolute time tocreate specific OID. Two specific OID can have time slots in twooperation frame which may be adjacent or not adjacent.

The radiation pattern of the stud IoT device that are located on sidecurbs 943 and 950 is towards the approaching moving objects 941 and 948.The same applies to stud IoT devices that are located on lane lines inFIG. 12A with a center barrier 946. The stud IoT devices 947 used bycenter barrier can have an Omni-directional radiation pattern or aradiation pattern that supports moving objects approaching them fromboth directions. The barrier type of radiation pattern is also appliedto stud IoT devices 952 used by lane lines in FIG. 12B.

Stud IoT devices in their broadcast packet share a lot of informationwith other IoT devices. The information in a stud IoT device as well assome other IoT devices are, number of slave stud IoT devices supportedwith a master stud IoT device, Location coordinates of stud IoT device,density of Fog, speed limit, road barrier stud, road side stud, numberof lanes in each direction, distance to a road curb, time stamp,distance to traffic light, animal crossing, type of road (freeway, dualcarriage, single lane, bridge, overpass, two levels, etc.) number ofroad lane on the left or right side in each direction, emergency lane,distance to next exit, traffic bump, color of traffic light, time leftto change the color of traffic light, height of tunnel, width of thetunnel. Length of the tunnel, distance to tunnel, number of lanes in thetunnel in each direction, no right turn when traffic light is red,slippery road, lane closed, diversion, snowing, black ice, heavy rain,raining, slope of the road, type of turn ahead, speed limit for theturn, hill or mountain at left or right of the road, valley at left orright of the road, animals on the road, downhill, uphill, type of stud(side of road, road barrier, first lane from left, second lane fromleft, . . . , first lane from right, second lane from right, etc.), rockfall, landslide, mudslide, avalanche, debris fall, rockslide,construction, blockage, caved in. For broadcasting these data, a “N”digit code can be used. For some data following the code a value isbroadcasted like speed limit. Some of the above information data arealso collected by various sensors that are used by master stud IoTdevice as well as slave stud IoT devices. The information data collectedby these sensors are send to SD to be stored and will be updated onregular time intervals. SD also have access to the above informationfrom other sources that monitor the weather, traffic, and status ofroads.

SD stores the information data about the detail map of environment,terrain type of the area stud IoT devices (master or slave) and any IoTdevice (master or slave) that operates within OCS. SOMC determines theOID for an IoT device (master, slave, and stud) based on the map, typeof terrain the IoT device operates in, and type of IoT device (IoTdevice used by NPS, stud IoT device, and type of object using the IoTdevice).

FIG. 12C shows a typical country road in mountainous area 980. The roadin mountainous area 980 is a single lane, two lanes (one in eachdirection) with or without center barrier, 3 lanes (one in one directionand two in another direction) with or without center barrier, four lanes(two in each direction) with or without center barrier, and any freewaywith multiple lanes and center barrier.

An IoT device (master IoT device) used by a moving vehicle in certainmountainous roads and tunnels does not receive signal from IoT networkand/or GPS. There are scenarios that IoT device cannot consistently seefour satellite to obtain time of day, and location coordinates. In thisscenario the stud IoT devices (mainly the master stud IoT device) usedby lane lines, center barrier, and roadsides also receive no signal orextremely low signal from IoT network and GPS. These stud IoT devicesare stationary IoT devices and when they are in mountainous areas ortunnel with no or week GPS and IoT network signal they do not have anyoperation information data (OID) to operate and provide information fora moving vehicle's navigation and protection system (NPS).

When a moving vehicle's IoT device (master IoT device) does not haveaccess to GPS and/or IoT network, unless it has an exactly accurateclock with sufficient hold over it is possible to lose TOD beforegetting out of a blind mountainous area or a tunnel. It will not be ableto update its location coordinate with the shared data base (SD) to beused by shared operation and management center (SOMC) to provide updatedOID for the moving vehicle. In this scenario there are two optionsavailable to the moving vehicle, one is use of manual mode for itsoperation and the other is to operate by relying on less informationthat its sensors obtain from environment. The second option may be OKinside a blind tunnel, but it is highly risky when the road is alongsidea cliff.

The above problems and limitation can easily be avoided or cured byusing various methods or solutions for GPS and IoT networks. Thesemethods and solutions are:

IoT Network

1. Use repeaters or relays at high elevation on top of mountains thatreceives strong signal from IoT network and relay it towards mountainousroad (any type of road explained earlier) and tunnels to provide highIoT network signal level for moving vehicles, flying objects and thedistributed antenna system (DAS) that provides coverage within thetunnels. DAS for tunnels is an organization of spatially placedantennas, coax, and splitters that provide radio frequency (RF) coveragewithin a structure or geological area that does not have adequate signallevels. Using this technique moving objects, flying objects, andstationary objects in mountainous areas with or without tunnels cancommunicate with IoT network to obtain TOD and OID which containsoperation information from SOMC. It also allows the above objects toupdate their information data in SD.2. A second approach is to install several grandmasters IoT devicespowered by solar cell at the top of surrounding mountains to communicatewith IoT networks to register, obtain TOD and receive the operationframe structure and an OID. Usually, some stationary objects in themountainous roads cannot communicate with IoT network. However, one ofthese grandmaster IoT devices can be assigned to several of thestationary IoT devices as their master IoT device to provide them withTOD and OID. If a moving object or flying object powers up in amountainous area after a period of power down it can also use one of thegrandmasters IoT devices on the top of mountains as a master IoT device,register with IoT network, obtain TOD, and OID. However, a moving objectduring power down usually saves and maintains its OID and may only needto obtain TOD from a grandmaster IoT device on top of mountains (in caseits hold over time for the TOD is finished) and continue operating itsNPS until gets out of the blind area and register again with IoT networkand update its location coordinates (when it has access to GPSsatellites). Grandmaster IoT devices have a fixed location coordinate,have GPS receiver, and may have sufficient hold over time when GPSsignal not available. A grandmaster IoT device's location coordinatesmay be used for stationary as well as moving objects. A grandmaster IoTdevice can adjust its location coordinates by its distance fromstationary and moving objects (as well as elevation) and report it toIoT network as the object's location coordinates.

The country road and mountainous road 980 shown in FIG. 12C has verytall mountains either side, a cliff next to the road which ends up in avalley, and a tunnel going through the mountains. The road has two lanesone in each direction. The reflector studs on the lane lines and theside curb studs act like FIG. 12B. In FIG. 12C there is a cliff on oneside of the road which makes it essential to have side curb Stud IoTs988 and 985 for better navigation of the moving object 990. It is alsoessential to have side curb Stud IoTs 986 and 987 on mountain side toachieve better navigation of moving objects. The lane line Stud IoTs 989radiate like the lane line stud IoTs in FIG. 12B to help navigation ofmoving object in both direction of the road. Side curb stud IoTs 986 and988 as well as lane line IoT stud 989 acts as master stud IoTs andsupport several slave side curb stud IoTs and lane line stud IoTs. Thetime slots in an operation frame and OID assigned to the side curb studIoTs and lane line stud IoTs by SOMC is based on the information relatedto the map of the road stored in SD. More than one time slots and theirabsolute times within said operation frame may be assigned to the mastercurb stud IoT, the master lane line stud IoT as well as the mastercenter barrier stud IoT if any exist.

IoT devices 981 and 982 at the top of the mountain act as bothGrandmaster IoT devices and IoT network relays. When act as grandmasterthey need to have GPS receiver with high holdover time for times thatGPS signal is not available for any reason. Grandmaster IoT devices 981and 982 also store a lot of the information of SD, and SOMC for when IoTnetwork cannot be accessed. Therefore, grandmaster IoT devices 981 and982 act as provider of TOD when GPS signal is not available and asSD/SOMC when IoT network is not available.

The stationary IoT device at the top of the entrance of the tunnel 983in FIG. 12C communicates with grandmaster IoT devices 982 and 981 (whenthey act as grandmaster IoT devices) to register with IoT network,obtain TOD and OID. Then IoT device at top of the entrance of the tunnel983 (as a master IoT device) propagates the TOD and OID or specific OIDto stationary IoT devices 984 inside the tunnel that are slaved to it.

FIG. 12D illustrate a typical junction 1100 of two freeways. Junction1100 is at the point where freeway A and B cross. Freeway B under passesfreeway A. Freeways A and B on each direction have two lanes divided bya lane line with lane line stud IoT devices (1107, 1108, 1109, 1110).Center barrier with center barrier IoT devices (1105, 1106) separate twodriving direction of the freeways A and B. Both freeways A and B useroadside stud IoT devices (1101, 1102, 1103, 1104) along their roadsideswith equal distance or random distance from each other. Light posts orpoles are used at roadside or center barriers at equal distances orrandom distances, Light posts also act as IoT devices to providenavigation information for moving vehicles. Light posts or poles (1115,1116, 1117, 1118) near exit of freeways A and B provide additionalinformation related to the exits a1 (1111), a2 (1112), b1 (1113), and b2(1114). Light posts or poles (1119, 1120, 1121, 1122) close to entrancesb1 (1113), b2 (1114), of freeway A and a1 (1111), and a2 (1112) offreeways B also share addition information to vehicles that enterfreeways.

Paragraph 00261 description of FIG. 13 provides a detail of all IoTdevices used to assist navigation of moving objects in freeways, one wayroads, two way roads, road junctions, freeway exits, turning right orleft and other scenarios that a moving vehicle encounters.

Freeways A and B also have traffic signs (1125, 1126, 1127, 1128),distance signs (1125, 1126, 1127, 1128), exit ahead sign(1125, 1126,1127, 1128), exit lane sign (1125, 1126, 1127, 1128), road exit sign(1125, 1126, 1127, 1128), next town or city sign (1129, 1130) thatprovide additional information related to the exits a1 (1111), a2(1112), b1 (1113), and b2 (1114). Light posts or poles (1123, 1124)located on the center barriers of freeways A and B also act as IoTdevices and provide navigation information data for moving vehicles onthe freeways and exit information data for those moving vehicles thattry to exit one of the freeways. The detail of all IoT devices is inparagraph 00261 description of FIG. 13 .

One scenario is when a moving vehicle travels from point 1 in freeway Ato point 2 in freeway B as shown in FIG. 12D. The moving vehicle mustexit the freeway A from exit a1 to enter freeway B. The moving vehiclebefore reaching exit a1 receive information data for its navigation fromIoT network (area map, distance to exit, exit lane, etc.) and IoTdevices at the roadside and center barrier. When moving vehicleapproaches the exit a1 the IoT devices on the roadside (roadside stud,light pole/post, exit sign, distance sign, exit ahead sign, next town orcity sign, road exit sign, exit lane sign, traffic sign, lane linestuds, center barrier studs, and center barrier light poles provideadditional information related to exit a1. This additional informationinclude distance to exit a1, exit lane for a1, speed to enter the exit,downhill or uphill exit, slop of exit in degree, number of lanes in theexit a1, length of exit a1, limited map around the exit a1, operationinformation data (TOD, frequency, channel, bandwidth, ERP, modulation,and wavelength) when entered exit a1, type of entrance to freeway B(right only, traffic light at the entrance to freeway B, left turn tofreeway B allowed with traffic light, lane for left turn on exit a1),the weight of vehicle to enter the freeway B, all or part of exit a1 isa tunnel, height of tunnel, speed limit is freeway B, and any otherinformation data (or any specific data) that facilitate smooth exit fromfreeway A and enter to freeway B. The same applies for moving vehiclesthat from point 3 in freeway B travel to point 4 in freeway A.

The main point in the above scenario is that when a vehicle tries toexit its own road/freeway to another road/freeway or turn left/rightfrom its own road/freeway to another road/freeway it has access tomultiple sources for information data for navigation. In case thevehicle losses access to IoT network or GPS and it does not haveholdover capability for TOD, then IoT devices that were discussed inparagraph 00233 to 00236 or 00261 can be used to obtain TOD. Inaddition, during loss of access to IoT network the vehicle uses IoTdevices discussed in paragraph 00233 to 00236 or 00261 for exiting,entering, turning left, or turning right to a new road/freeway. Movingvehicles in a freeway/road can be a car, a SUV, a truck, a motorcycle,and any moving vehicles that are allowed to use the freeway/road.

FIG. 12E illustrate a typical two-way road 1200. Two-way road 1200 canbe any two-way road in the country, village, town, city, and any roadthat connects two cities, towns, and villages. Two-way road 1200 shows atypical road within a city, town, or village. The roadside 1201 and 1202can be sidewalk for pedestrians. Roadside may use roadside studs (IoTdevices) 1203 and 1204 alongside of the road to facilitate navigation.Alongside of the road 1200 there are lamp (light) posts (1205, 1206),trees (1207, 1208) buildings (1209, 1210), IoT network base stations(1211, 1212), electric/mailbox 1213, lane divider 1214, lane lines IoTstud 1215 and moving vehicles 1216.

As mentioned in paragraph 00261 the information that building IoTdevices shares with moving vehicles in two-way road 1200 are the height,type (concrete, metal enforced, wood structure), length, characteristicof building in their vicinity, and if there is any GPS (1217) blockage.Trees, mailboxes, electric boxes, and any other stationary objectalongside the road act like other stationary objects (includingbuildings) and provide information data to facilitate navigation ofmoving vehicles and objects. The stationary objects at certain locationsalongside the road 1200 provide additional information data tofacilitate navigation of moving vehicles and objects.

FIG. 12F depicts road 1300 that is like road 1200 with an inlet from aone-way road constituting a T junction with right turn only. The one-wayroad has its own sideroad 1218, sideroad stud IoT 1219, lamp post/pole1220, tree 1221, building 1222, and moving vehicle 1223. All stationaryIoT devices provide information data to facilitate navigation exceptthose in vicinity of the T junction. The stationary IoT devices close tothe T junction provide additional information data for moving vehicle1223 that includes distance from junction, condition of the two-way roadit is entering, if there is a stop sign or traffic light, closestvehicle to the junction in the road it is entering, speed limit in theroad it is entering, if there is a yield sign at the junction, If thereis traffic in the road it is entering and any other information thathelps entering. The moving vehicle 1223 also detects if there are anyother moving vehicles in the main road. If there are send them anEthernet or broadcast packet and request allowing it to turn right tothe main two-way road. If a moving vehicle respond to entering request,proceed to enter the main two-way road. The additional information datacan be anything that is specific to the T junction.

FIG. 12G illustrate a four-way junction 1400 with traffic light. Bothroads of four-way junction 1400 are two-ways with moving vehicles inboth directions. Both two-way road A and B are like FIG. 12D. Road A hasthe identifiers used in FIG. 12D and road B has its own identifiers forroadsides (1418, 1419), roadside stud IoTs (1420, 1421), lamp posts(1422, 1423), buildings (1424, 1425), base stations (1426, 1427), trees(1428, 1429), mail or electric box 1430, lane line 1431, lane line studIoT 1432, and moving vehicle 1433. At each corner of the junction 1400there is a pole with traffic lights 1234. Each pole with traffic lightcan support one or more of the following typical structures thatcommonly used.

a). three distinct light fixtures for red, yellow, green color formoving vehicles going straight.

b). a single light fixture for turning left that shows a left arrow withgreen, yellow, or red color.

c). a single light fixture for turning right that shows a right arrowwith green, yellow, or red color.

There are structures for traffic light that can be used for specificjunctions like a T junction, a pedestrian crossing traffic light, atrain crossing traffic light, an animal crossing light, and any otherapplications.

The lanes ahead of traffic light may also be assigned for turning left,right, or straight by painting direction arrows inside the lane. A lanemay also show two or three arrows, left/straight, right/straight, andright/straight/left.

The IoT devices (lane lines studs, roadside studs, trees, traffic signs,distance signs, buildings, lamp posts, etc.) ahead of traffic lights ortraffic light IoT device can also broadcast the lanes used for left,right, or straight. In case the junction 1400 uses stop sign, then eachmoving vehicle requires to stop and move when it has right of way.Moving vehicle before approaching the four-way junction obtains detailinformation of the junction from the IoT devices mentioned above. As thevehicle get closer to stop or stops at the junction it can obtain fromabove IoT devices and the other moving vehicles in the junctioninformation data that allows it to determine when it has right of wayand can move. The same principle applies to moving objects at Tjunctions or any other kind of junctions like roundabouts.

FIG. 12H shows a freeway with an entrance 1500. Usually, freeways do nothave trees or buildings in their vicinity that can be used as IoTdevice. FIG. 12H shows a typical freeway with an entrance for movingvehicles from another road or freeway to enter. Freeway with an entrance1500 has roadsides 1501, 1502, center barrier 1503, and the entranceroad also has roadside 1504. The IoT devices that freeway with anentrance 1500 uses are roadside studs (1507, 1508, 1510), lane linestuds (1511, 1512), center barrier studs (1509), and light post/pole(not shown in FIG. 12H) that are located along the freeway and theentrance. Along the freeway there are other objects like base stationtowers (1516) that can be used as IoT devices. These IoT devices assistnavigation of moving vehicles 1513, 1514, and 1515. The IoT devices invicinity of entrance provide additional information data for movingvehicle 1515 and moving vehicle on the freeway that are approaching theentrance. Some of the information data are, distance to entrance, yieldsign, stop sign, traffic light (color), speed of approaching entrance,speed limit of freeway, type of lane, and any other information thatmoving vehicles require for a smooth entrance.

All the information data mentioned in above paragraphs are digitallycoded and broadcasted with in a broadcast, an Ethernet, or a proprietarypacket or packets. The OCS with GPS, IoT network, SD, SOMC, and allstationary IoT devices can also be used by moving/flying vehicle(object) with an operator (driver, pilot) to automatically take controlof the moving/flying vehicle (object) when the operator trying toperform a navigation act that results in an accident. In this scenariothe moving/flying vehicle (object) NPS takes over all navigation devices(steering wheel, break, accelerator, all navigation devices of a flyingobject, etc.) and controls the moving/flying vehicle (object) to avoidany imminent accident. This happens when an operator is under influenceof drug or alcohol, suffers a heart attack, suffers a stroke, losevision, is young and inexperienced, and any other condition that resultsin an accident. In other words, the AI within NPS monitors all detectedinformation data from various objects or IoT devices (moving objects,flying objects, and stationary objects) and the information data itreceives from IoT network (SD, SOMC) and use them to decide how and whenthe navigation devices (steering wheel, acceleration, break, indicators,light, etc.) and protection devices (airbags, compressed air, expandedpads, etc.) need to be activated. If an operator of moving/flying objecttries to activate these devices outside the limits that AI allows, thenAI interferes and stops the driver/pilot. AI has control of allnavigation and protection devices, and it stops the operator to make adangerous activation move. In cases when the operator does not perform anecessary activation, then AI will perform the activation for theoperator.

FIG. 14A depict the object control system OCS frame structure 80 definedby SOMC. Frame structure 80 has a frame TOD 81 that indicates the startof first frame, duration 82, and end TOD 83, a start guard time 84, atime slot 85, a start of time slot or absolute time 86, and an end guardtime 87. After the end of end guard time 87 the next frame starts. Frame80 accommodates “n” time slots where “n” is an integer and is defined byOCS. All time slots in a frame can have the same duration or differentdurations. An IoT device is assigned a time slot (TS) with an absolutetime that is the start of IoT device's first time slot (TS). The IoTdevice TS duration is defined by SOMC based on the object'sspecification. The IoT device is also aware of the frame duration anduses this duration, and its absolute time to calculate the TOD for thestart of its next TS which is a calculated next absolute time by the IoTdevice.

Frame 80 uses the start guard time and end guard time to avoid any frameoverlap due to slight error in the TOD of various components and IoTdevices of OCS. It is always possible to use one guard time at the startor end of the frame. The TOD of the various IoT devices is regularlyupdated to eliminate any accumulation of TOD error (jitter). The guardtime (start or/and end) can be used by SOMC to update operationinformation data (OID) for various components and IoT devices withinobject control system (OCS).

The frame 80 duration and structure are not the same for all smartenvironments. Moving and flying objects with high speed will havesmaller frame duration whereas moving objects in metropolitan smartenvironment can use longer frame duration. Therefore, the duration andstructure of frame depends on several parameters. These parameters aretype of objects, frequency band that IoT devices operate, bandwidth ofchannel used for operation, speed of data transmitted and received,maybe size of the object, type of road or streets, type of smartenvironment (city, urban, suburban, towns, villages, country roads,desert, forest, coast), type of cell (terrestrial, satellite), and otherparameters that are needed for a safe smart environment.

SOMC through IoT network communicates with a master IoT device used byan object (NPS). Master IoT device must conform to all requirements ofthe IoT network defined by standard committees. Master IoT device alsocommunicate with NPS's controller to exchange OID (obtained from SOMC orupdated by controller AI algorithm) and send detected information data(DID). Slave IoT devices communicate with NPS's controller to receivethe OID and send their DID. NPS's controller is aware of features andcapabilities of the slave IoT devices. NPS allows slave IoT devices tooperate if the requirement defined by SOMC is fulfilled. Theserequirements are minimum requirement for an object's NPS to operate indifferent smart environments.

SOMC may assign more than one time slots to an IoT device. The assignedtime slots to the IoT device can be adjacent or in different location inthe frame duration. If they are adjacent, then SOMC assigns one absolutetime which is the start of the first time slot in the adjacent timeslots. If the time slots are not adjacent, then SOMC assigns an absolutetime for each time slot. IoT device uses the absolute time and frameduration to calculate the absolute time for the next frame.

SOMC as shown in FIG. 14B can assign a subset of time slots to all IoTdevices for their communication with the IoT network, shared database SDand SOMC. The IoT devices can simultaneously communicate with IoTnetwork using the subset of time slots assigned by SOMC. In the start ofNPS operation, master IoT device communicates with IoT network in anormal way to obtain OID. However, if master IoT device performs otherfunctions, then after it receives the OID at the start, then itcommunicates with IoT network during the time windows defined in theframe structure.

SOMC can also assign a subset of time slots to IoT devices used byflying objects. Flying object's IoT devices use fixed, mobile, or loworbit satellite base station (eNodeB, gNodeB, or proprietary) tocommunicate with IoT network and SOMC to receive the frame information,their time slots, and absolute times. Flying object's IoT devices canalso use terrestrial base stations (eNodeB, gNodeB, or proprietary) tocommunicate with IoT network and SOMC to receive the frame information,their time slots, and absolute times.

SOMC can also assign two independent frames, one to IoT devices attachedto (registered with) terrestrial base station and another frame to IoTdevices that are attached to (registered with) mobile or satellite basestations. The terrestrial and satellite frames can have independentdurations and start TOD. In one scenario satellite frame with itsindependent frame duration starts when terrestrial frame ends.Therefore, there are two tandem frames with a total duration. In thiscase an IoT device uses the total duration of two frames and its ownabsolute time to calculate the absolute time of its next time slot. Inthis scenario SOMC may assigns the same channels or wavelengths to IoTranging devices attached to (registered with) terrestrial and satellite(or mobile) base stations.

In the second scenario satellite and terrestrial frames are totallyindependent and have their own independent duration and start TOD. Inthis scenario SOMC required to assign different and independent channelsand wavelength to the terrestrial and satellite cells. Therefore, therewill be no interference between terrestrial and satellite channels andwavelengths. However, effective radiated power (ERP) of IoT devices mustnot be high to avoid any receiver blocking.

FIG. 14C depicts the duration of a time slot 31 used for ranging,communication (broadcast packets, Ethernet packets), and monitoring bythe wireless system 970 (or IoT device 400 shown in FIG. 4 ) The timeslot 31 comprises of guard time (1) 32, ranging time 33, guard time (2)34, communication (broadcast packets, Ethernet packets) time 35, andguard time (3) 36. The start of time slot is the absolute time 30assigned to a wireless sensor system 970 (or IoT device 400 shown inFIG. 4 ) or NPS of an object. Time slot 31 can be all assigned tomonitoring task, communication task, transmission/reception of broadcastpacket task, transmission/reception of Ethernet packets task, or rangingtask. Time slot 31 can also be assigned to two tasks, three tasks, fourtasks or all five above tasks.

The guard times at the beginning and end of the time slot is to avoidany overlap between two adjacent time slots and tasks. Although IoTdevices obtain their time of day (TOD) from GPS, eNodeB, or gNodeB of 5G(6G, 7G), WiFi router, or private IoT network but it is possible thattheir TOD are different with reasonable error (jitter). The error(jitter) does not accumulate because the TOD is updated on regularbasis. The start and/or end guard time should be bigger than the highesterror (jitter) in TODs. The guard time between ranging time and the timeof other tasks is to avoid overlap and time for processing of data.

In another embodiment, the SOMC through IoT network (4G, 5G, 6G, 7G andbeyond), the WiFi network or the private network shares with eachwireless sensor system 970 (or IoT device 400 shown in FIG. 4 ) in asmart environment the absolute time and time slot of all the registeredwireless sensor system 970 (or IoT device 400 shown in FIG. 4 ) in thesmart environment. All absolute times and time slots are stored in ashared database (SD) and are managed by a shared operation andmanagement center (SOMC) used by all service providers and operators.

During the time slot the IoT device's wireless channel (propagationchannel) should not change. The maximum time that a channel is constantand does not change is “coherence time” and the maximum channelbandwidth that the fading is flat is “coherence bandwidth”.

Coherence bandwidth is proportional to average channel delay spread. Ifaverage delay spread is larger than symbol time, then the channelexperiences frequency selective fading which results in inter symbolinterference (ISI). To avoid selective fading or ISI the symbol timeshould be larger than average delay spread. Therefore, if the symboltime is Ts and the average delay spread is C^(r) then we need to meetthe following condition.Ts>C ^(r) or1/Ts<1/C ^(r) orBs<Bc

Where Bs is symbol or channel bandwidth, and Bc is the coherencebandwidth.

Coherence time is proportional or related to Doppler frequency shift orchange. When IoT ranging device is moving with respect to an object inthe smart environment or both IoT ranging device and the object aremoving then the frequency of reflected signal from the object changesdue to motion. The change in frequency is proportional to theapproaching speed of the object towards the IoT ranging device. If thecarrier frequency is Fc and approaching speed of object towards the IoTranging device is V, then the Doppler shift Fd is:

Fd=V·Fc/Vl, where Vl is velocity of light in free space. The coherencetime Tc is the time that the channel is approximately constant. Tc isrelated to Doppler shift by following equation.Tc=(¼)(1/Fd)

The ranging pattern for wireless sensor 970 (or IoT device 400 shown inFIG. 4 ) can have two different structures. In one structure the patterncomprises of the ranging pattern only. In a second structure the rangingpattern comprises of a synchronization (preamble) pattern followed byranging pattern. In first structure ranging pattern is used for bothsynchronization and ranging. Using a synchronization pattern reducesresolution of detection. If the length of pattern is reduced, thenprobability of false detection increases. To increase the resolutionwithout reducing the length of the ranging pattern higher channelbandwidth needs to be used. However, higher channel bandwidth requireshigher carrier frequency, smaller delay spread and lower relative speedor approaching speed to avoid violation of coherence bandwidth andcoherence time. Lower delay spread limits the radius of ranging andlower approaching speed or relative speed limits the speed objects canmove in a smart environment.

One way to overcome the above problem is to convert the ranging patterninto smaller segments. The IoT ranging device or wireless sensortransmit each segment of ranging pattern signal then receives thereflected segment followed by transmission of the second segment andremaining segments like first segment. Depending on application one canuse zero or more segments as synchronization (preamble) segment ofranging pattern. Let us assume the maximum speed of moving object is 100miles/hour, then every millisecond the object moves 4.5 centimeter. Iftwo objects in smart environment moving towards each other with 100miles/hour, then every millisecond they get closer about 9 centimeterand every 3 milliseconds around one foot. Therefore, if the two objectsare 3 meters apart and their approaching speed towards each other is 200miles/hour then they collide after 33 milliseconds. This time issufficient for a navigation and protection system (NPS) to obtainrequired information data, to decide and to activate appropriate devicesand functions to avoid a collision.

Let us assume the radius for ranging and monitoring (sending broadcastand Ethernet packets and receiving broadcast and Ethernet packets) is 3meters. In this scenario IoT device is used for ranging and monitoringby moving objects (automobile, robots, etc.) and stationary objects insmart environment. If the IoT device is connected to external body ofmoving object and stationary object, then for a radius of 3 metersaverage delay spread should not exceed 4 nanoseconds (IoT device usesdirection antenna with narrow radiation pattern to avoid higher delayspreads). IoT device ignores received signals (reflected, broadcast,Ethernet) that are from objects at a distance more than three meters bymeasuring the RSSI of a received signal and compare it with a table ofRSSI versus distance or uses TOD of transmission and reception ofranging signal.

FIG. 14D depicts the duration of a time slot 41 used for ranging,communication (broadcast packets, Ethernet packets), and monitoring bythe wireless sensor system 970 (or IoT device 400 shown in FIG. 4 ). Theonly difference between FIGS. 14C and 14D is that ranging is performedbefore end of time slot 41 and everything else is the same.

In another embodiment, wireless sensor system 970 (or IoT device 400shown in FIG. 4 ) is aware of the absolute times and time slot durations(if time slot durations are different) assigned to all other wirelesssensor systems 970 in its smart environment or operation frame.

In another embodiment, all wireless sensor systems 970 (or IoT device400 shown in FIG. 4 ) in a smart environment are registered with one ormore IoT networks (4G, 5G, 6G, 7G and beyond), WiFi networks or privatenetworks that are linked and share (SOMC, and SD), control and managethe information (function, type, location, etc.) received from allwireless sensor systems 970.

For a navigation and protection system (NPS) to operate in allcircumstances an artificial intelligent (AI) algorithm is used thatreceives information data from following source:

-   -   a) All internal sensors used by an object.    -   b) Wireless sensors, Radars, Image sensors, Lidars, laser, and        ultrasonic sensors that perform ranging to provide a distance        between two objects.    -   c) Image sensors that provide the same information as wireless        sensor as well as image identification of the objects.    -   d) IoT devices that in conjunction with IoT network provide a        distance and an approaching speed of the two objects towards        each other using time of day (TOD) time stamps.

AI algorithm requires information data from at least three of the abovesources to be able to decide intelligently. Having access to more thanthree sources' results in a more accurate decision and better supportfor navigation and activating the most effective devices withinprotection system.

FIG. 14E shows cell planning 70 for object control system OCS used bythe IoT network. Cell planning 70 shows hexagonal cells 71 but othercell shapes can also be used. Cell planning 70 shows threechannels/wavelengths. These three channels/wavelengths C0/L0 (72), C1/L1(73), and C2/L2 (74) are reused to cover the entire IoT networkcoverage. The cells can also be numbered for better identification. Itis also possible to use a single channel or wavelength (C0/L0, or one ofthe other C1/L1, or C2/L2). The channel (C0, C1, and C2) bandwidthdepends on the frequency band in the frequency spectrum. These channelsare used for ranging, broadcasting, communication using Ethernetpackets, monitoring, data collecting, data sharing and other functions.Channel bandwidth and center frequency must meet the requirements of thecoherence bandwidth and coherence time. It is always possible to haveother channel planning and cell planning. In case of LIDAR, Laser, orinfrared L0, L1, and L2 that are the wavelength of the wave is used. Itis also possible to have a cell planning that all cells use the samefrequency, bandwidth, wavelength and when a moving object moves from onecell to another cell it does not need to change its frequency,bandwidth, and wavelength. However, it may need to change its time slotand absolute time. The change of time slot and absolute time can comefrom SOMC. When IoT network is not available moving objects need to finda time slot within the operation frame that is vacant and use that timeslot for operation and continue operation this way (find a vacant timeslot and use for operation) until IoT network become available. Movingobject from information that it receives from a boundary stationaryobject recognizes that it is entering a new cell.

The terrain map of the cells, cell's number, critical peripheralcoordinates, location coordinates of important objects (buildings withheight, stationary objects like traffic lights, junctions, roundabout,different turns, tunnels, bridges, mountains, valleys, river, sea, lake,exits, construction work, closed road, one way or two ways roads,direction of traffic, type of roads, streets, lanes, etc.), andinformation about any critical object (such as stationary objects thatshare detail of operation frame, number of time slot, time slotstructure, number of cell, frequency and channel bandwidth, wavelength)in a cell is stored in the SD to be used by SOMC of OCS. A criticalobject can also be a stationary object located at the boundary of cellsto share the new cell information data explained above.

A moving object at regular times updates its location coordinates in SD.Location coordinates is obtained by a simple low-cost GPS receiver and amaster IoT device used by the object sends it to SD regularly. GPSreceiver can update the location coordinates from as low as every 50milliseconds to one second depending on complexity of GPS receiver. Amoving object through its master IoT device updates its locationcoordinates in SD. The position coordinates can also be estimated by atriangulation algorithm that uses stationary objects in vicinity ofmoving object. Stationary objects in the vicinity of moving objects havefix position coordinates. This is done when moving object's GPS can notsee the GPS satellites.

The cells are assigned an operation frame structure shown in FIG. 14A.The structure and duration of the operation frame can be the same forall cells. The best approach is to have operation frames with the sameduration for all cells. This way only the structure of the frame istailored to the cells. And in the structure of operation frame the onlything that may be different is duration of time slots assigned tovarious moving objects. If all moving objects follow a requirement fortheir specification defined by the standard, then all time slots willhave the same duration and structure. Therefore, SOMC can use identicaloperation frames for all cells in OCS.

When a cell is congested and the operation frame does not havesufficient time slots to assign to various objects in the cell, thereare four options to overcome this problem. First option is to reduce theduration of a time slot. This requires increasing the bandwidth of thechannels that further requires increasing the carrier frequency of theIoT ranging transceiver. As a result, doppler frequency increases orcoherence time decreases, coherence bandwidth increases which requireslower delay spread to avoid inter-symbol interference, and operatingrange of IoT ranging device decreases. Second option is to reuse thetime slots that are used for stationary objects when they aresufficiently apart and do not introduce interference. Second option haslimited application and solves the problem for certain cells. Thirdoption is to increase frame duration (for all cells) to accommodate allobjects within a cell. This option also has a limited application and isnot suitable for cells that have moving objects with high speed becauseit can affect the accuracy of the ranging data obtained by variousranging techniques and cause cell structure of the terrain map morecomplicated. The final and fourth option is to divide a regular and maincell to smaller cells within the main cell and assign the same operationframe to smaller cells within the main cell. This scenario happens incities with objects moving with lower speed and freeways with heavy andslow traffic. The smaller cells will have shapes (circle, triangle,square, hexagon, etc.) that fit inside the main cell. It is alsopossible to use a combination of the above options without making theOCS complicated.

The start time of the operation frame shown in FIG. 14A is set by aspecific TOD for all cells and cell's channels/wavelengths (C0/L0,C1/L1, and C2/L2). Since the duration of operation frame does not changethen SOMC assigns absolute TOD for every time slot that is used bymoving objects. The absolute time is assigned based on the start TOD ofthe operation frame and the number of frames already passed after thestart TOD. Once a moving object knows its absolute time, from durationof the operation frame it can calculate its next time slots, and thiscontinues even when a moving object moves from one cell to a neighboringcell with a new channel/wavelength (for example moving from C0/L0 toC2/L2). The timing of everything stays the same (when a moving object inits new cell changes its operating channel/wavelength) and the objectstill uses the same absolute time and time slot that was given to it bySOMC at the start of its operation.

It is possible when an object moves from one cell to another cell SOMCassigns a different time slot and absolute time to the object. If thisis the case, SOMC before the object enters the new cell informs theobject the new time slot and absolute time (TOD) which indicates thestart TOD of the time slot.

Three issues need to be discussed here. First is time of day TOD and howit is obtained. TOD is based on coordinated universal time UTC that isprovided by satellite to GPS receivers (American GPS, Galileo, GLONASS,and BeiDou). This time is used by various objects for differentapplications. In data communication system some components of the systemuse GPS and directly obtain the TOD. It is also possible to centralizethe GPS receiver and through a master port propagate the time of daythrough data communication network using IEEE1588 PTP. So, what happensif something goes wrong with the satellites or GPS receiver? GPSreceiver that produces TOD uses an oven control crystal oscillator orrubidium clock (Atomic clock). These two clocks are very stable and caneasily have hold over time up to 24 hours or even more.

The moving (stationary) object also can use a very stable clock (OCXO,or atomic clock) and obtain the time of day from GPS receiver. The costof these clocks has come down and if the volume goes up the cost will benegligible compare with the price of moving (stationary) object. Thesetypes of clocks can maintain the TOD accuracy within acceptablethresholds for NPS of moving (stationary) object. In addition to lowercost the accuracy and performance of these clock is improving.

Second is the transition of a moving object from one cell to aneighboring cell. Question is how a moving object detects if it hastransitioned to the neighboring cell? SOMC has knowledge of the locationcoordinates of each moving object that is updated every second or less.Moving object using its low-cost GPS receiver obtains the locationcoordinates and sends it to SD through its master IoT device. In case oflosing GPS satellites or problem with GPS receiver a moving object canestimate its location coordination using the location coordinates ofstationary objects in its vicinity using triangulation becausestationary objects position coordinates are fix and does not change.Therefore, SOMC will inform the moving object through the operationinformation data OID that it has transitioned to a new cell (SD has thecoordinates of peripheral of each cell, and cell number) and thechannel/wavelength it needs to use during its time slot.

The third issue is the location coordinates of a moving object when GPSreceiver loses the satellites or cannot see 4 satellites (problem withsatellites, satellites not in operation, or satellite is jammed/spoofed)to be able to calculate the location coordinates. In addition toAmerican GPS system there are three other systems from Europe, Russia,and China (Galileo, GLONASS, BeiDou) that can be used to obtain locationcoordinates. There are GPS receivers that can work for all systems.Therefore, the probability that all systems have problem is exceedinglysmall.

Location coordinates help during transition to a new cell by a movingobject. If this information is not available one solution is for movingobject NPS to ask its slave IoT devices to detect all threechannels/wavelengths (C0, C1, C2, L0, L1, and L2) until the problem goesaway. A second solution is to switch to manual operation until theproblem is resolved.

Stationary objects in a cell have fixed position coordinates and alwayshold and share operation frame (duration, start time, number of timeslots, time slot duration, operation frame's number which is resets atspecific TOD, etc.) information data in their broadcast (Ethernet)packet. Moving objects in a cell if they lose communication with IoTnetwork for any reason can acquire operation frame information data froma stationary object broadcast (Ethernet) packet. As explained earliermoving objects can also estimate their location coordinates bytriangulation using the position coordinates of the stationary objectsin their vicinity. In other words when GPS and IoT network signals arejammed, spoofed, very weak, not relayed by reflectors or repeaters, ortemporary not available a moving object has access to operation frameinformation data, and can estimates its location coordinates fromstationary objects in its vicinity and its NPS can continue itsoperation. Moving object can also from stationary objects that are atthe boundary of cells identify that it is moving to a new cell and getthe information data its NPS needs from boundary stationary object.

In case of flying object, the same operation frame shown in FIG. 14A canbe used and some time slots can be assigned to flying objects. This wayinterference in OCS is eliminated. The flying objects before reachingthe desirable and assigned elevation (altitude) by SOMC may use the samechannels and wavelengths SOMC assigned to terrestrial moving objects andwhen they reach to assigned elevation (altitude) use the same channelsand wavelengths but in a larger cell structure shown in FIG. 6 .

Flying objects may also have their own operation frame andchannels/wavelength assigned to them by SOMC. In this scenario duringtakeoff and landing they may need to switch to terrestrial operationframe and channels/wavelengths.

Finally, when moving objects like an automobile is parked on the streetit is considered as a stationary object and it can either turn its NPSoff or leave it on. If the NPS is left on, then the slave IoT devicesthat are facing the street function and the automobile still uses theterrestrial operation frame and time slot assigned to it. Solar powermay be used when the automobile is parked on the street to preserve thebattery.

Threats to both services and data are growing in volume and complexity,making it harder to keep up with the constantly shifting securitypicture. Similar attacks are becoming more prevalent on other kinds ofinformation-based smart networks as well, such as those that operatebuildings, utility systems and intelligent traffic systems. Whether theobjective is to steal intellectual property, halt operations or tamperwith data, the tools and the techniques used for unauthorized networkaccess are increasingly sophisticated.

There is increasing concern regarding cybersecurity across industrieswhere companies are steadily integrating field devices into network wideinformation systems. This occurs in discrete manufacturing and processindustrial environments, a wide range of general and specific purposecommercial buildings, utility networks, and even intelligent trafficsystems or networks. Traditionally, electrical systems were controlledthrough serial devices connected to computers via dedicated transceiverswith proprietary protocols. In contrast, today's control systems areincreasingly connected to larger enterprise networks, which can exposethese systems to similar vulnerabilities that are typically found incomputer systems.

Since inception of self-driving cars there has been various types ofattacks on different units of self-driving cars, such as the internalmeasurements unit, LIDAR, RADAR, GPS, Camera, Thrust monitoring unit,Application unit, etc. In such attacks, a vehicle does not prepare asecure sequence of moves to maneuver in a tight place. For vehicles thatare not fully autonomous some typical attacks include Sybil attack,denial of service attack, timing attack, message tampering, illusionattack, and node impersonation. These attacks are also applied to fullyautonomous vehicles but are not subject of disclosure in thisapplication. This application discloses attacks associated with wirelesscommunication and means of detecting and mitigating them for moving,flying and stationary objects. These attacks can be flooding attacks,data playback attacks, data alteration attacks, blackhole attacks, spamattacks, and cryptographic replication attacks. This application focuseson attacks that alter the information data (TOD, OID, and DID) used fornavigation.

The NPS of vehicle/object (IoT device) 900 as a component of objectcontrol system OSC that communicates with IoT network, SD, and SOMC isprone to cyber-attack. Cyber-attack can tamper with the information data(TOD, OID, and DID) NPS uses for navigation and protection. This canresult in various accidents and loss of life. Cyber-attack can also beused to assassinate passengers of a moving vehicle or guide a robot todo criminal acts. There are several ways that cyber-attack on a NPS canhappen. There are two very critical and easy ways of cyber-attack. Oneis through master IoT device that communicates with IoT network (WiFi,5G, 6G, beyond 5G and 6G) and a second way is through slave IoT deviceof NPS that collect DID. It is also possible to attack through Bluetoothand other wireless capabilities that moving object 900 possesses. IoTdevices used by NPS (master and slave) broadcast their information whichinclude operation frame information explained in FIGS. 14A, and 14B, atime stamp that indicate TOD at their antenna port, location coordinate,identity number, type of object, and other information data. They alsosend these information data in any Ethernet packet that they send toanother IoT device. Master IoT device of a NPS receives OID whichincludes TOD from IoT network. Master IoT device can also obtain TODfrom GPS. NPS has access to all these ports and their data (TOD, OID,DID, locations, etc.) and uses its AI algorithm to create a signatureand reject any information data which does not match the signature.

To attack an object's NPS the attacker has three options. One is jammingboth master IoT device and slave IoT devices. This action results injamming all objects with an NPS in vicinity of attacker which results inchao. Therefore, this approach can not be used if a particular objectwith NPS is targeted. Second is Jamming GPS that results in all objectswith NPS lose access to their location coordinates and some to updatetheir TOD. However, the location coordinates of stationary objects arefixed and does not change. An object's NPS through master IoT device orslave IoT device obtains the location coordinates of stationary objectsin its vicinity and by exchanging time stamps estimates its distancefrom a stationary object then from these two data estimates a reasonablyaccurate location coordinate. To avoid losing TOD during jamming,object's NPS can use a clock with long holdover during which TOD is holdwithin acceptable drift. If an object's NPS does not have a clock withlong holdover it can obtain as well as update its TOD by requesting froma nearby NPS that have a clock with holdover.

The third type of attack is a targeted and specific attack at anobject's NPS. This application discloses various ways that a specificattack can be carried out and ways to mitigate the attack. This specificattack is based on altering the data that a NPS needs to operatecorrectly. The data are detected information data (DID), time of day(TOD) and operation information data (OID). The important data in OIDare absolute time, time slot duration, operation frame duration, andoperation frame start time. Operation frame structure and time slotstructure are usually part of a standard known by NPS or obtainedthrough IoT network (from SOMC and SD). Slave IoT devices used by theNPS provide their DID which includes operation frame duration (receivedfrom IoT devices in surrounding environment), operation frame starttime, mac address of slave IoT devices belonging to objects in vicinityof NPS, distance from slave IoT devices belonging to objects in vicinityof NPS (using time stamps), distance from objects in vicinity of NPS(using ranging radar, Lidar, image sensor, or ultrasonic sensor), RSSIof broadcast or Ethernet packets received from stave IoT devicesbelonging to other objects, location coordinates of objects in vicinityof NPS received from their broadcast or Ethernet packets, the TODcalculated from exchange of time stamps with slave IoT devices belongingto objects in vicinity of NPS. Master IoT device communicates with IoTnetwork, obtains TOD and OID which includes operation frame duration,the start time of operation frame, an absolute time, and a time slot forNPS.

The above TOD, DID, and OID can be altered by cyber-attack. If TOD thatIoT network provides for the NPS is altered due to an attack, then allthe NPSs that get their TOD from that IoT network will be affected. IfTOD that GPS provides for NPS is altered due to an attack, then all NPSsin vicinity of attacker will be affected. However, a sudden change whichrequires higher than normal update to TOD can be easily detected. Theamount of TOD increment and higher than normal number of consecutiveincrements in a specific period can be sign of an attack by imitatingIoT network. The same applies to master IoT devices of NPSs that obtaintheir TOD from GPS. TOD can also be obtained by NPS's slave IoT devicesby exchanging time stamps as described earlier. Since there are severalslave IoT devices in vicinity of NPS it means that multiple sources ofobtaining TOD need to be attacked to alter TOD. Therefore, altering TODfor an attacker is not a good option due to multiple sources and ease ofdetecting.

An attacker can intercept communication between an NPS's master IoTdevice and IoT network to obtain operation information data, time slot(TS) information, absolute time for the TS and other information relatedto operation of NPS. The operation information data that an NPS receivesfrom IoT network are operating carrier frequency for ranging, operatingchannel, bandwidth, data rate, over the air protocol, in case of Lidaroperating wavelength, and effective radiation power.

To attack through a slave IoT device an attacker needs to acquire TOD,operation frame duration, operation frame start TOD. By knowing thesethree parameters an attacker may be able to interrupt operation of anNPS. TOD can be obtained from GPS. Operation frame information can beobtained from a stationary NPS or a moving NPS as explained earlier byusing the time stamp of two consecutive broadcast packet of an NPS'sslave IoT device, master IoT device or by detecting the information datashared in broadcast or ethernet packets. The time slot duration can becalculated from time stamps of two adjacent packets. An attacker canalso obtain the operation frame structure and timings from an IoTnetwork.

FIG. 15 shows cyber-attack mitigation 1000 using a signature. Anattacker tries to alter the information data (TOD, OID, and DID) tointerrupt or force an NPS make a wrong decision which results in anaccident with possible loss of life. As shown in FIG. 15 , NPS 1001obtains its operation information data by master IoT device 1002 throughIoT network 1008 (from SOMC and SD) which uses a terrestrial radio unit(RU), a mobile RU (which is a flying balloon RU or a low earth orbitsatellite RU) as well as slave IoT device 1003 (from other object'sslave IoT device 1007). The information data (TOD, OID, and DID) isreceived by NPS's controller 1004 and for decision making theappropriate data is sent to artificial intelligent (AI) algorithm.Controller creates a signature from the information data it receivesfrom master IoT device and slave IoT devices as well as GPS. All thesedevices (1002, and 1003) can provide TOD, operation frame duration,operation frame start time, absolute times for the time slots slave IoTdevices receive from a broadcast or ethernet packet, absolute timemaster IoT device receives for NPS, RSSI of received broadcast (orEthernet packets), distance from an external object using ranging(LIDAR, RADAR, Ultrasonic), mac address of external slave IoT device1007, distance from slave IoT device 1007 through exchange of timestamps, time stamp received by slave IoT device 1003 or master IoTdevice 1002 from a broadcast or Ethernet packet of an external slave ormaster IoT device 1007, type of object uses slave or master IoT device1007, weather and environment conditions from slave or master IoT device1007, traffic light status from slave or master IoT device 1007, andidentity code of the NPS (object) that an external slave or master IoTdevice 1007 uses.

The signature is in form of a database table that its first column isthe identity code (source of data) for those objects in the environmentthat have NPS (moving, flying, and stationery), GPS and IoT network.Column one also identifies four (rear, front, left, and right of themoving object with NPS) rows for each ranging device Radar, Lidar,Ultrasonic, and Image sensor. So, column one is identity code for thesource of data. Column 2 shows type (model) of the object that data isobtained from, column 3 is the MAC address of the objects with NPS(source of received data) in surrounding environment, column 4 belongsto distance of the object in the surrounding environment from NPS (wheresignature resides), column 5 shows the TOD obtained from an object withNPS (in surrounding environment) using time stamp (by the object withNPS where signature resides), and column 5 also shows TOD obtained fromIoT network or/and GPS by the object with NPS where signature resides.Column 6 shows the operation frame duration obtained from IoT network,and objects with an NPS in surrounding environment (by the object withNPS where signature resides). Column 7 stores the operation frame starttime obtained from IoT network and other objects with NPS (by the objectwith NPS where signature resides). Column 8 is the absolute timereceived from IoT network and from NPS of other objects in surroundingenvironment (by the object with NPS where signature resides). Column 9is the received RSSI of a slave IoT device belonging to an object's NPSin surrounding environment (of the object with NPS where signatureresides). Column 10 is the ERP of the objects with NPS in surroundingenvironment (of the object with NPS where signature resides). Column 11shows the time stamp received from NPS of objects in surroundingenvironment (of the object with NPS where signature resides). Column 12is the weather and environment condition received from other objectswith NPS (by the object with NPS where signature resides). Column 13 istraffic light status received from traffic light objects with NPS (bythe object with NPS where signature resides). Column 14 is miscellaneousdata received from various objects (by the object with NPS wheresignature resides). Columns of the signature database table withvariable data (distance, RSSI, time stamp, weather condition for cameraand image sensor, traffic light status, and miscellaneous data) have adefined tolerance. In case of the columns of the signature databasetable with fixed data (operation frame duration, start of operationframe, ERP, TOD, absolute time, and weather and environment conditionfor camera and image sensor), if the data from one source changes, it isexpected that data from other sources change to the same value. Anexample is operation frame duration. If an IoT network changes operationframe duration, then all objects attached to the IoT network changetheir operation frame duration to the new value at the same time. TheNPS receives the fixed data from different sources, and it is not easyfor an attacker to alter these data. If this happens and an attackeralters these data through one of the sources, by using the signaturedatabase table it will be detected and ignored and the attacker will beidentified and may be reported to IoT network and other objects.

Based on the above if an attacker imitates the IoT network it can onlyalter the fixed operation data that an object's NPS obtains from IoTnetwork. Since the object's NPS also obtains the TOD, structure ofoperation frame (duration, and start time), and absolute times fromother sources (object's NPS) in its vicinity and all these data are inits signature database table it will easily detect by its controller'sartificial intelligence (AI) whether the operation information data fromIoT network is from an attacker.

If an attacker tries targeted attack to alter data through slave IoT ormaster IoT device of an object's NPS then it requires to synchronize itsoperation with the object's NPS. To do this attacker first needs toobtain TOD from GPS or IoT network. Next attacker needs to obtainoperation frame information. There are two ways of obtaining operationframe information and they are:

a) register with IoT network as a moving object with an NPS to obtainoperation frame information, a time slot, and an absolute time. At thispoint attacker can transmit and receive broadcast and Ethernet packets.To attack a specific object's NPS the attacker needs to find the addressof broadcast or Ethernet packet of the object's NPS. Attacker firstneeds to identify the time slot of the object's NPS that wants toattack. This is not a simple task unless attacker gets close to theobject's NPS that is subject of attack. Let's assume that attacker findsthe time slot of the object's NPS. Attacker cannot alter any of thefixed data that object's NPS uses for operation because object's NPS hasmultiple sources for the fixed data in the signature database table. Ifobject's NPS does not use other devices for ranging (Radar, Lidar,ultrasonic sensor, or image sensor) to provide distance of other objectsin the surrounding environment, then the attacker may be able to forcethe object's NPS make a wrong decision by activating the wrongprotection device or navigation device which may results in accident andloss of life. This is not easy because the attacker must get severalparameters right. These parameters as explained elsewhere are operatingfrequency band, operating channel, operating modulation, operating delayspread, Doppler shift, ERP, and RSSI. The probability that attacker hasall the parameters right is extremely low and if the attacker getseverything right the worst decision that the AI of an object's NPS makesis to activate the protection devices. If attacker imitates a trafficlight and try to broadcast fake traffic light information the fake datawill be detected because object's NPS has the surrounding area mapinformation. If there is a traffic light, object's NPS receives thetraffic light status from broadcast packets from various sources in itssurrounding environment and from traffic light IoT device 1007.b) obtain TOD from GPS or IoT network, then monitor broadcast packetsand Ethernet packets from objects in surrounding environment that haveNPS. Next attacker can retrieve time stamp from two consecutivebroadcast packet belonging to the same source to obtain operation frameinformation. Attacker also can retrieve time stamp for two consecutivepackets that belong to two different sources to calculate a time slotduration. Once attacker obtains all these data, next needs to find thetime slot that belongs to the object's NPS targeted for attack. Anattacker can also obtain most of above operation information data bydetecting a broadcast packet or Ethernet packet from an object invicinity of attacker provided the data is not encrypted and if the datais encrypted it can decrypt the data.If attacker obtains all these data, like the scenario that was explainedabove faces a very difficult task to make the object's NPS that is beingattacked to make a wrong decision.Various embodiments are thus described.
